hey buddy, that is human nature, not limited to chinese.
1. recalled in late 90s, americans rushed into internet bubble stocks and suffered huge loss after the bubble crashed starting april 14, 2000.
2. recalled in early/mid 2000s, poor and less previledged people (in addition to rich people) rushed towards real estate bubble ambitiously to grab the wealth, little thinking r.e. price may drop someday.
3. last week, george soros sold 99.4% of his positions in gold accumulated/built in the past years. how come gold price has surged from <$300 to above $1500 in 5 years? there are always insane people to follow the rising tide.
so, a smart person is: 1. if you think you are capable, go with the tide but quit at or near the peak; 2. if you don't think you can, stay away from it, always be calm to simply watch without participation.
