The amount of funds used by CSYB to purchase the shares of common stock was $280,000. All of such funds were provided by CSYB.

Item 4. Purpose of Transaction.

The securities of the Company acquired by CSYB were acquired in order to gain control of the Company. Following the acquisition, CSYB owns approximately 56.62% of the issued and outstanding common stock of the Company. Other than as set forth below, the reporting persons currently have no plan or proposal which relates to or would result in any of the actions or transactions described in paragraph (a) through (j) of Item 4 of the instructions to this Report.

On April 28, 2010, the Company entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) by and among CSYB, Belmont Partners, LLC (the “Seller”), and the Company. Pursuant to the terms of the Purchase Agreement, on April 28, 2010, CSYB acquired from the Seller 1,299,000 shares (the “Purchased Stock”), or approximately 56.62%, of the issued and outstanding common stock of the Company. In consideration for the sale of the Purchased Stock, CYSB paid the Seller $280,000 and the Company agreed to issue to the Seller shares of its common stock (the “Issued Stock”) such that the Seller will own 5% of the issued and outstanding capital stock of the Company after the closing of a merger transaction with an as of yet unidentified target corporation contemplated by the Purchase Agreement.

Pursuant to the terms of the Purchase Agreement, the then current officer and director of the Company resigned on the closing date and Mr. Meng and Mr. Chin were named as directors and as President and Secretary of the Company, respectively. Such resignation and appointment were effective as of the closing date with respect to the officers of the Company. The resignation of the current director and the naming of Mr. Meng and Mr. Chin as directors will take effect on the tenth day following the mailing by the Company of an information statement that complies with the requirements of Section 14f-1 of the Securities Exchange Act of 1934.
