/KOOC-0/992/KOOC-0/0/KOOC-0/0 In October, Hong Kong TVB broadcasted the TV series "Big Times" starring Adam Cheng. The story tells the story of Ding Xie, played by Adam Cheng. When the stock market was in a bear market, he often made huge profits by shorting the Hang Seng Index futures. At this time, the Hong Kong stock market plummeted and investors suffered heavy losses. Hence the name "Ding Crab Effect".

Since then, almost every time Adam Cheng's TV series, movies or programs are broadcast, the stock market will drop sharply, and Adam Cheng is equated with "stock market crash". According to incomplete statistics, after Adam Cheng's TV series and programs were broadcast, the stock market experienced 32 obvious declines.

The worst time is 1997. Once the legend of the legendary Jianghu man was broadcast, the Hang Seng Index fell below 10,000 points. Coincidentally, during the Asian financial turmoil of 1998 and the bursting of the internet stock bubble in 2000, TV dramas appeared in Adam Cheng, and the theory of "Ding Crab Effect" spread like wildfire. "As soon as Crab Ding comes out, the stock market will collapse", a golden rule in the eyes of Hong Kong investors, is widely spread.

Adam Cheng's daughter, Zheng Xinyi, was also accused of being the same as her father, Adam Cheng. The broadcast of a drama is bound to make Hong Kong stocks plummet. On June 20th, 2008, 10, the sitcom "Beating One's Own" premiered. Some investors complained that the broadcast of the drama made the Hang Seng Index in Hong Kong show a downward trend every day again, and netizens called Zheng Xinyi "an enhanced version of Ding Crab Effect 2.0".
