(Beijing) – A link between "House Sister" Gong Aiai and Pan Shiyi, the chairman of SOHO China, has become a hot topic on the Web in China.

It has also caused the share price of the major property developer to fall 8.6 percent to HK$ 6.28 on February 6.

Gong's story is an illustration of China's unwritten rules, namely that a back door can be used to get around the law in any field, in this case the real estate sector. The fact is that for the privileged and rich this back door is an entrance to huge personal gain.
