ITEM 1A. RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the following risk factors and information provided in this annual report and other filings. If any of the following risks actually occur, our business, financial condition, or results of operations could be materially and adversely affected.

Risks Relating To Our Business

We have no operating history and no signed contracts at this time and our operating results are unpredictable.  

We have no operation history.  Since the Company's formation, we have not realized any revenue yet. We do not have any signed contracts with any customers at this time. There is no historic data or pending agreements upon which our investors could evaluate, estimate or predict our future revenue and profits. The likelihood of our company's success must be considered in light of the risks, uncertainties, expenses and difficulties frequently encountered by companies in the early stages of development.

We will incur increased costs as a result of being a public company, including the adoption of Sarbanes-Oxley Act, which may not be affordable to us.

Rules adopted by SEC pursuant to Section 404 of Sarbanes-Oxley require annual assessment of our internal control over financial reporting, and attestation of this assessment by the Company’s independent registered public accountants. These requirements may result in changes in corporate governance practices and to develop an adequate internal accounting control to budget, forecast, manage and allocate our funds and account for them, while simultaneously developing and organizing our business.  As a development stage company, these new rules and regulations will increase our legal, accounting and financial compliance costs and will require additional staff time. Since we have limited financial resources and staff time, we may not be able to afford the increased costs, which ultimately could cause investors to lose their investment.

Our auditors have raised substantial doubt about our ability to continue as a going concern.

Because we do not have sufficient working capital necessary to pursue our business objectives, our auditors have expressed their opinion that we may fail in the future if we do not generate revenue and profits in the near future. This opinion must be disclosed to

3

all potential investors and other sources of capital, which may adversely affect our ability to raise capital. Shareholders and creditors' confidence may be low in evaluating our Company. If we are successful in acquiring a loan or a line of credit, we may be charged a much higher interest rate because of our financial condition.

Our only Director, Mr. Hong has limited financial capability, and needs to run his additional business interests. He may be unable to devote his full time, or even honor all his financial commitments to the Company, and eventually cause you to lose your investment if his outside business fails.

Mr. Hong, our President and sole Director, personally bears the costs of bringing this company public, and bears the loans for the operation of this company. He has limited financial capability, for example he recently took a personal credit line of $200,000 from a bank to help him to cover his personal expenses, including his personal investment in our company.  Mr. Hong has paid about $15,000 per year from his personal accounts to cover the company’s basic costs, such as auditing and SEC filing, without charging the company due to his verbal agreement that he will not charge the company until it has a positive cash flow.  Additionally, he is running an additional business to generate the income to support his operation of this company. He owns Crown Assets Administrative LLC, a Taiwan registered company, and he is the Chief Secretary of Ma-Friend organization, which was organized with the election of President Ma, Ying-Jeou, Republic of China (Taiwan). Mr. Hong devotes about 30 hours per week to the company.  The activities of his additional business may occupy a significant amount of his time, which may result in interruptions or delays in our customer service for our Company.

Mr. Hong's limited financial capability also may cause him to be unable to honor all his financial commitments with the Company, and eventually to cease the operation of the Company, and cause shareholders to lose their investment.

We face strong competitors, which may force us out of business:

There are numerous competitors existing in Taiwan management and financial consultation business: such as Abeam Taiwan, LADO Management Consultants Ltd., etc, which have greater financial resources, longer operating history, brand name recognition, and superior marketing than us. We compete with them by targeting an underserved market, which are small companies, typically managed by an owner personally or an owner’s family only, which lacks the experience of running a stock cooperation or a public company. There is no guarantee that our strategy will work since our company

4

doesn't have any operational history. Even if we have the clients in the future, the competitors' aggressive pricing may greatly reduce our revenue and profits margin. We may never be success if we fail to compete with our competitors.

We have no business insurance; any unanticipated events or expenses may hurt our business substantially.

We have no general liability or umbrella liability insurance to cover legal issues due to claims of negligence; no key personnel insurance to protect our company from a key person dies, falls ill, or leaves; no criminal insurance to protect us from theft and malicious damage. Any unanticipated events or expenses may hurt our business substantially.

If we grant employees share options or other share-based compensation in the future, our net income per share could be negatively affected.

If we are forced to pay employees or business cooperators with stock, or stock options for services already performed, we may substantially reduce the value of each share.

Our sole director controls our Company, which could result in a lack of independence needed on certain issues and decisions, which could impact shareholders.

Our sole director, Mr. Hong currently owns 90% of the outstanding common stock, remaining in control of the Company.  Although Mr. Hong is not party to any voting agreement, he will be able to exert significant influence, or even authority, over matters requiring approval by our security holders, including the election of all of our directors, control our operations, and inhibit your ability to change the Company's operations.  Accordingly, our shareholders will not have sufficient votes to cause the removal of Mr. Hong in his function as officer and director.

As a result, we lack independent directors, independent board committees and an independent audit committee financial expert. There can be no assurance that Mr. Hong will be completely independent in the decisions he makes as our sole director and/or principal stockholder that will ensure protection of the rights of other stockholders who purchase our securities in this offering.

Such concentrated control of the Company may adversely affect the price of our common stock in the event we merge with a third party or enter into a transaction which requires shareholder approval.

5

Operations outside the United States may be affected by different local politics, business and cultural factors, different regulatory requirements and prohibitions between jurisdictions.

Operations outside the United States may be affected by different local business and cultural factors, different regulatory requirements and prohibitions between jurisdictions, including the Foreign Corrupt Practices Act and local laws prohibiting corrupt payments; and changes in regulatory requirements for financing activities.

We are working in the emerging markets (i.e. nations with social or business activity in the process of rapid growth and industrialization). The developing nature of these emerging markets presents a number of risks and uncertainties. For example, after the new President Ma charged Taiwan government in 2008, his One China policy (meaning no intention to separate Taiwan from Mainland of China permanently) greatly improved economy cooperation between Taiwan and Mainland of China, and brings new economic development opportunities in Taiwan, which indicates that the political environment has significant influences on Taiwan's economy and our potential business. Any change of One China policy by the Taiwan government will have negative effectiveness on our future.

Risks Related to Our Securities

We must comply with penny stock regulations, which could effect the liquidity and price of our stock.

The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in "penny stocks." Penny stocks generally are equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or quoted on NASDAQ, provided that current price and volume information with respect to transactions in such securities is provided by the exchange or system. Prior to a transaction in a penny stock, a broker-dealer is required to: Deliver a standardized risk disclosure document prepared by the SEC; Provide the customer with current bid and offers quotations for the penny stock; Explain the compensation of the broker-dealer and its salesperson in the transaction; Provide monthly account statements showing the market value of each penny stock held in the customer's account; Make a special written determination that the penny stock is a suitable investment for the purchaser and receives the purchaser's consent; and Provide a written agreement to the transaction.  These

6

requirements may have the effect of reducing the level of trading activity in the secondary market for our stock. Because our shares are subject to the penny stock rules, you may find it more difficult to sell your shares.

We do not anticipate paying any cash dividends in the foreseeable future, which may reduce your return on an investment in our common stock.

We do not plan to pay any cash dividends in the foreseeable future. Any return on your investment would derive from an increase in the price of our stock, which may or may not occur.

There is no trading market for our common stock and quoting our stock price on the Over-The-Counter Bulletin Board increases the volatility of our stock and makes it harder to sell our stock.

Our common stock is not eligible for trading on any stock exchange and there can be no assurance that our common stock will achieve listing on any such exchange. Currently, our stock prices are quoted on the Over-The-Counter Bulletin Board. The Bulletin Board tends to be highly illiquid, in part because there is no national quotation system by which potential investors can track the market price of shares except through information received or generated by a limited number of broker-dealers that make markets in particular stocks. There is a greater chance of market volatility for securities that trade on the Bulletin Board as opposed to a national exchange or quotation system. This volatility may be caused by a variety of factors, including:

  a). The lack of readily available price quotations;

  b). The absence of consistent administrative supervision of "bid" and "ask" quotations;

  c). Lower trading volume; and

  d). Market conditions.

In a volatile market, you may experience wide fluctuations in the market price of our securities. These fluctuations may have an extremely negative effect on the market price of our securities and may prevent you from obtaining a market price equal to your purchase price when you attempt to sell our securities in the open market. In these situations, you may be required to either sell our securities at a market price which is lower than your purchase price, or to hold our securities for a longer period of time than you planned.

7

Investors may suffer substantial dilution or an unrealized loss of seniority in preferences and privileges if we need to seek additional funding in the future.

We have authorized 60 million common shares with only about over 1 million shares outstanding. If we desire to raise additional capital in the future we will experience possible losses, and the company has little assets in current operations, or we need to expand our operations, then we may have to issue additional equity, preferred securities or convertible debt securities, which may not need the approval of current shareholders. The issuance of new shares would cause the buyers in this offering to suffer dilution of their ownership percentage. The dilution may be substantial if the maximum of 60 million would be issued, the dilution would be approximately fifty times, or the current shareholder's ownership would be reduced to about 1/50. In addition, it is possible that any future securities could grant new shareholders rights, preferences, and/or privileges that are different from this offering.

Sales of the common stock by Mr. Hong may cause the market price for the common stock to decrease.

Total of 1,102,500 shares of common stock were sold to Mr. Hong at a price substantially less than the offering price of the shares being offered to investors in the offering. If he decides to sell any of his common stock in the future, those sales may cause the market price of the common stock to decrease. However, all of the shares of common stock owned by Mr. Hong are restricted securities as defined under Rule 144 of the Securities Act; meaning his stock may be eligible for sale after a period of six month, subject to timing, limits of sale quantity, and sale restrictions.

Item 5. Market for Registrant’s Common Equity and related Stockholder Matters.

Our common stock, par value $0.001, is listed on the Over-The-Counter Bulletin Board ("OTCBB") under the symbol "UCHN" (now RDTK). The trade price was traded between $2.00 to $0.10 with limited volume.

When applicable, such over-the-counter market quotations reflect inter-dealer prices, without retail mark-up, mark-down or commission and may not necessarily represent actual transactions.

b. Holders

As of March 31, 2012, we had approximately 45 registered stockholders of our common stock on record. This number includes shares held by brokerage clearing houses, depositories or otherwise in unregistered form.

c. Dividends.

On September 19, 2011, the Board of Directors of the company made decision: to distribute 1,230,000 shares of common stock of USChina Venture III Inc on par value $0.0001 per share to the shareholder as a gifts from USChina Venture III Inc. USChina Venture III Inc is an inactive company without assets except the treasury shares. These shares will be distributed to the shareholders of the company on one to one basis that is every outstanding share of USChina Taiwan will get one share distribution of USChina Venture III Inc. The record day of the shareholders of the company for the distribution is October 3, 2011.

Prior to the change of control of the registrant on December 31, 2012, the registrant distributed its shareholdings of USChina Venture III, Inc. to its shareholders.  Current management has been unable to obtain the information necessary to confirm that the distribution was consistent with Section 5 of the Securities Act of 1933.  Under Section 5, no security may be offered, sold, or delivered unless a registration statement is in effect as to the security, or an exemption from registration is available.   As a result, the registrant may be liable for civil penalties under the provisions of Section 5.

d. Securities Authorized for Issuance under Equity Compensation

None.

e. Recent Sales of Unregistered Securities

On April 6, 2011, the company issued 5,000 restricted shares, valued at $5 for outside services.

ITEM 9A. CONTROLS AND PROCEDURES

Controls and Procedures.

Evaluation of Disclosure Controls and Procedures:

We maintain disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to insure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, rules processed, summarized and reported within the periods specified in the Securities and Exchange Commission’ and forms and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, or the persons performing similar functions, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our CEO and Treasurer, or the persons performing similar functions, our management has evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this annual report. Based on that evaluation, our CEO and Treasurer, or the persons performing similar functions, concluded that our disclosure controls and procedures were not effective as of March 31, 2012.

Management’s Annual Report on Internal Control over Financial Reporting:

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is the process designed by and under the supervision of our CEO and CFO, or the persons performing similar functions, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external reporting in accordance with accounting principles generally accepted in the United States of America. Management has evaluated the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework.

Under the supervision and with the participation of our CEO and CFO, or the persons performing similar functions, our management has assessed the effectiveness of our internal control over financial reporting as of March 31, 2012, and concluded that it is effective.

10

Evaluation of Changes in Internal Control over Financial Reporting:

Under the supervision and with the participation of our CEO and CFO, or those persons performing similar functions, our management has evaluated changes in our internal controls over financial reporting that occurred during the year ended March 31, 2012. Based on that evaluation, our CEO and CFO, or those persons performing similar functions, did not identify any change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Important Considerations:

The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud.

Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time. Because of these limitations, there can be no assurance that any system of disclosure controls and procedures or internal control over financial reporting will be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.
