premise: Chinese financial stocks, which took the lead of going up, sunk the most, with financial index of H-shares declining 207 points, or 2 percent, wiping out the previous gains in one session.
  Even the successful land auction by the Hong Kong government Tuesday can not suspend the going down of the stock market. One of the land was sold at a price of 75 percent higher than the base price but only sees the stocks of real estate falling down at larger pace.
  Cheung Kong, the property giant of Hong Kong's tycoon Li Ka-shing, fell 5.08 percent after the company gained one of the auctioned land. However, Li said he believed the successful land auction Tuesday reflects the property industry's confidence in Hong Kong's economy.
   What is the fact that stocks sunk making refrence to?
hypothesis: financial index of H-shares declining 207 points
