If you dare to draw a line just because someone gives you a strategy or a point, I suggest you don't play contracts.

There are all kinds of charlatans in the square, and they are mixed.

There are those who are trapped and want others to help them; there are those who are stubborn and become two-faced; there are those who pull you into the group and want to suck your blood for a long time; there are also a group of people who are just conspicuous and are just jumping around.

In such a complex social environment, if you don't have any judgment ability, you are just wasting your money.
