What do you mean by unworthy children?

Unscrupulous descendants is an idiom in China, which refers to those who can't inherit their ancestral businesses and have no future.

Unfilial descendants are not idioms, but mean unfilial to their elders.

The definition of unfilial is very popular, that is, disrespect, unfilial and failure to support parents. And the meaning of corruption, if you haven't studied ancient Chinese, many people will be confused.

The so-called "Xiao" can be understood as portrait and appearance, and according to the interpretation of Shuo Wen Jie Zi, it is "flesh and blood". The popular understanding is that children and grandchildren look like their parents, and "not secular" means that they look different from their parents. It is further extended that children are not as good as their parents and have no talent.
