The fluffy hemp grows in the hemp, and it will straighten itself without support;

The white sand is in nirvana, and it is afraid of the dark.

The wood is straight in the rope, and it is rubbed into a wheel, and its area Medium rules

Those who are close to vermilion are red, those who are close to ink are black,

Natural selection, survival of the fittest

Birds of a feather flock together, people divide into groups

I don’t know that a person looks at his friends, not only his father, but also his son

A tiger father has no dog son,

A wise minister is close to a good minister, but a villain is far away

People are products of society
