Since he once held an important position in the Materials Department and has been the chairman of the Mid-term Group, Tian Yuan’s dual and special identity increases the possibility of his relationship with Zhang Wenzhong. In the early 1990s, the materials department where Tian Yuan worked at that time also had close ties with Chengtong Group. Data show that China Chengtong Group was established in 1992 by the merger of material circulation enterprises directly under the Ministry of Materials and Materials. During the planned economy period, these enterprises were responsible for the acquisition, allocation, warehousing, and distribution of important national production means. According to people familiar with the matter, the asset of Wumart Mall originally belonged to China Chengtong Group, but objectively speaking, this asset was not operating well at the time. Due to perennial losses, Chengtong Group decided to dispose of its assets, and Zhang Wenzhong took advantage of this opportunity to acquire the assets. On November 21, 2003, Zhang Wenzhong successfully listed Wumart Commercial on the Hong Kong Stock Exchange. At that time, it was a good year for commercial circulation companies, and Zhang made a lot of profits. Wumart Commercial's 2003 listing prospectus did not disclose in detail the initial composition, funding sources and shareholder background of Wumart. In fact, after Wumart went public, the major shareholder Wumart Investment itself is still operating retail businesses such as hypermarkets, and has not injected all of it into the listed company. In 1994, Wumart Mall, the predecessor of Wumart Investment, the major shareholder of Wumart Commercial, was established with a registered capital of RMB 75 million. Some media reported that China International Futures Brokerage Company is also one of the shareholders. Since the listing of Wumart Commercial, China International Futures Brokerage Company has been sending representatives to serve as independent supervisors of Wumart Commercial. Previously, in the prospectus, the long-term and short-term liabilities of listed Wumart Commercial were zero, which also aroused the curiosity of many observers. Zhang Wenzhong once said: "There are two models for cooperation between Wumart and state-owned enterprises: one is to take over the original assets, which is actually the payment of lease fees; the second is to standardize the restructuring and conduct a comprehensive evaluation of the original assets. On the basis of net assets, Wumart injects cash, so there is no need to bring the liabilities of state-owned enterprises to listed companies. "Obviously, compared with Zhang Wenzhong's acquisitions of commercial enterprises since 2003, Wumart was first established. The process of obtaining pots of gold is much more complicated. Zhang Wenzhong talked about the reason why he returned to China after studying and went into business. In addition to the support of his mentor at Stanford in the United States, he also included the encouragement of Tian Yuan. Investigation This newspaper learned that as the investigation of Zhang Wenzhong and Tian Yuan deepened, the issue of the source of Zhang Wenzhong's acquisition funds when he originally purchased Wumart assets was involved. According to reliable sources, it is likely to be related to guarantees for bank loans.
