By looking up "Close Contact" by official website, the TV series Mahjong, I learned how simple it was for Zhao Tianyu to speculate on futures with the company's 300 million yuan, and swept away 300 million yuan in one sentence. Zhao Tianyu set up an overall situation, recruited a group of swindlers, got $300 million to invest in the stock market, and fired his own company's shares, which eventually became $738 million.

Close Contact of Mahjong is an urban commercial war drama produced by Beijing Luhuaina Film and Television Co., Ltd. and Tianjin Culture and Art Audio and Video Publishing House, directed by Liu Jiang and starring Yu Hewei, Summer Xu, Yin Tao, Wang Bozhao, Bao Lei and Xia Meng.
