The general manager of the securities investment department was involved in a 760 million yuan "rat warehouse" scandal, not making money but instead being fined 4.5 million yuan.

On November 11, the administrative penalty decision announced by the China Securities Regulatory Commission's Heilongjiang Regulatory Bureau showed that Tang Mouming, the general manager of the securities investment department of a securities company, was fined 4.7 million yuan for trading with undisclosed information and for the improper trading of stocks by employees. The administrative penalty decision showed that Tang Mouming bought stocks totaling 762.91 million yuan by controlling the use of other people's accounts for coordinated trading and by using undisclosed information to suggest or imply others to engage in related transactions. Additionally, he also bought stocks totaling 140.10 million yuan in the Shanghai and Shenzhen stock markets by controlling the use of other people's accounts. Ironically, Tang Mouming's above-mentioned actions "did not result in any illegal gains," meaning he did not make money. However, because his actions were illegal, the China Securities Regulatory Commission's Heilongjiang Regulatory Bureau decided to impose a fine of 4.7 million yuan on him. Of this amount, Tang Mouming was fined 4.5 million yuan for his "rat trading" behavior.
