How to express the sentence that uncle is a father?

My nephew misses his uncle's words, but he expresses them in different ways.

Using father to describe uncle, maybe we are really not ignorant.

Miss your uncle's words, you have to start a new life again.

In a word, praise your uncle. You stumbled a long way.

Expressing love will also be missed, and describing what you may have read will be the best source and motivation.
