I cannot understand the China's stock market

The stock index is so high, next step which direction will it go?
I am not clear, but I know that there are lots of danger, we should be careful and careful.
Last time after the Industrial Bank got a price more than the City Bank, the index fell off about 100 points, my fund also fell off nine percent. At that time, money was enough, people were running into the market, but the market clashed, this time, the index is too high again, will it clash again?
I always remember a word: if you cannot understand something, just stop doing it!
For more than one week, I have not bought any stocks, though my fund increased more than one cent each day!
