Definition

不是一家人,不进一家门

Literally means:

there must be a reason why people become a family

Actually means:

Figuratively it means that people with different personalities or interests usually do not associate with each other. It implies that people who often cling together are usually agreeable with each other and enjoy each other's company.

比喻性格、志趣不同的人不会聚到一起。隐含字面以外的意思:能聚在一起的人,就是彼此投缘的人,就成了一家人了。
