The website cites a document from China's commerce administration to claim Zhang's 66-year-old mother Li Zhuosheng, is among 112 individual shareholders and 11 investing corporations of Dalian Wanda Commercial Properties.

The Wall Street Journal estimated Wanda's IPO could raise $5 - $6 billion while Wanda's estimated value overall might reach $60 billion after the shares start trading.

The huge success of Alibaba's launch on the New York stock market last week pushed its chairman and founder Jack Ma into the No 1 spot on the list of the Chinese mainland's wealthiest people. However, the former richest man in China, 60-year-old Wang Jianlin, the founder and chairman of Dalian Wanda Group, might well regain the top spot after the Hong Kong flotation.

The document obtained by Jiemian.com shows Li Zhuosheng purchased nine million shares in December 2008 and thereafter went on to own 18 million shares, 0.46 percent of total stocks of Dalian Wanda Commercial Properties. The website calculated these shares would soon be worth 1.6 billion yuan ($260.8 million).

Jiemian.com said the retired mother actually holds these shares for her star daughter who has a close relationship with a 57-year-old wealthy businessman named Ding Mingshan, Chairman of China Wallink and also a big shareholder of Wanda Commercial Properties.

Zhang and Ding haven't responded to the website request for comment about the link of Wanda shares. Zhang Zinan, brother of the actress, said only, "I have no idea."
