China's stock market is dangerous!

China's stock market is more than 1600 now, many people run into the market to buy stocks, and even the bad news for the market is read as good news, what's the problem? What has caused this to happen?
I think there are at least two reasons, first is many foreign money believes the Renminbi will increase in a short and medium period, so they put their my money in the house or stock, and investing in the stock market is more hideous, after Renminbi has reached a certain level, they will change the stock into money and then run away; the second reason is that people all want more money, and they cannot keep calm head before this circle of investing, so also invest their money into the stock market which is too hot, it is dangerous to do so!
the development of one healthy stock market is ensured by the healthy development of companies, but china's companies all go to the stock market to drink money like blood, they do not add any new money into the stock market!! After the Renminbi has reached a certain level, the foreign money will quit, and the stock market is sure to decline, at that time money of china's investors will shrink, so i think it is wise not to pack into the stock money in three years, just like the house market!
