Your theory is uneducated. Try to figure the price of your theory.
The Chinese do not give a shit about quarterly results. Your suggesting they do indicates a lack of understanding of how they view their economy.
I guess we will see tonight around 6pm when the futures open.
As said elsewhere, if one has a basic education and common sense, it is normal to be concerned. But concern shouldn't turn to hysteria and speculation whereby people short the market. Btw, the quarterly GDP issue is part of a broader concern about China's fundamentals. The govt DOES care about capital flight and so, yea, actually they DO care about bad economic press.
Futures markets or any market opening is strong-form efficient, but not necessarily accurate. We will see where this lands.
