Let's take a look at the comments that only idiots would make:

1. Will the dog dealer fall down to do charity for you? Is it to let you get cheap chips?

2. Adhere to the attitude of being bearish but not shorting.

3. ETFs have already appeared, how could it plummet?

4. (It has already risen from 20,000 to 70,000, a record high) Now is the early stage of the bull market, and it is going to sprint to 100,000!
