The Securities and Futures Commission investigated a customer named Jiang. More than 60,000 futures companies scattered in about 10 companies combined with the spot market to control the market, which triggered the retreat of market speculative forces and led to the market diving.

Jiang Shibo, a native of Zhuji, Zhejiang, aged 38, is the vice president of Zhejiang Dida Futures (his brother Jiang Yibo is also engaged in futures, and vice president of yongan futures). He likes to be a ST hat-taking stock, mainly doing the hat-taking market from the end of the year to the first quarter, and doing roller coasters in suning universal, Wanxiang Denong and Yantai. The backstage boss of Dida Futures is the famous Zhejiang Tong Yuan Group. Tong Yuan Group mainly sells mechanical and electrical products and automobiles, ranking first in the national mechanical and electrical industry. Jiang Shibo's buddy is only a sophomore, and he has been in and out of many stocks such as Saier. Miao Qinwen, Jiang Shibo's sister, has been in and out of Yantai Ice Wheel, Wanxiang Denong and other stocks at the same time. Gao Yaping, a relative of Grade Two, a colleague and buddy of Song Jianjun and Jiang Shibo, and the vice president of yongan futures, have all been in and out of Wei Shi of Wanxiang Denong, and all of them are in ST Wolong. Their investment ideas are the same and have nothing to do with Jiang Shibo and his gang. These black villages also manipulate Japanese rubber and help to speculate on Shanghai rubber.
