Since April, a waiter at a high-end restaurant in Beijing has made the equivalent of eight months salary on the bullish Chinese stock market, xhby.net reported on Monday.

The waiter surnamed Xu learned which company's stock to purchase by overhearing a group of diners at the restaurant. Xu memorized the stock code the diners had most frequently mentioned, then spent three years of savings to buy shares in the company, according to the report.

Xu said the restaurant's business has been thriving since mid-May, especially on weekends, thanks to the patronage of stock investors.

Chang Hao, an investor from Nanjing, capital of Jiangsu province, said many Chinese stock investors have set up discussion groups on QQ, a popular instant messaging service, and members take turns inviting others to dinners or organize get-togethers.

Chang said the dinners are intensive – he has attended three or four on weekends, most of which were on Saturdays.

Many stock investors say the exchange of information and ideas during such get-togethers is good, allowing them to correct mistakes, seize market opportunities and even get psychological support.
