We are formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination with one or more businesses or entities, which we refer to throughout this prospectus as our initial business combination. Our efforts to identify a prospective target business will not be limited to a particular geographic region or industry. We do not have any specific business combination under consideration and we have not (nor has anyone on our behalf), directly or indirectly, contacted any prospective target business or had any substantive discussions, formal or otherwise, with respect to such a transaction with our company. Our ability to identify and evaluate a target company may be impacted by significant competition among other SPACs in pursuing a business combination transaction candidate and the significant competition may impact the attractiveness of the acquisition terms that we will be able to negotiate. We will seek to capitalize on the significant contacts and experience of our management team, including Mr. Ping Zhang, our Chairman, Chief Executive Officer, Chief Financial Officer and director, and Mr. Wei (Victor) Zhang, Mr. Daniel M. McCabe, and Ms. Qi Gong, each of whom will become a member of our board of directors upon the effectiveness of the registration statement of which this prospectus forms a part. We believe we can leverage our team’s track record to identify and execute attractive acquisition opportunities. --- We intend to focus our efforts on identifying and completing our initial business combination with a company that aligns with our team’s experiences, expertise and network of relationships. Our business strategy is expected to be focused on potential acquisition targets that exhibit compelling long-term growth potential and highly defensible market positions. We believe this will allow us to generate a differentiated pipeline of acquisition opportunities and lead to executing a business combination with an attractive target company more quickly, efficiently, and under better terms than our competitors. Our principal office is located New York, NY.
