In ancient Chinese, Shen means "Shen", which is homophonic with fish. "Shen fish" means "Shen fish", which means that beauty is a stone. Your family name starting with "Shen Yu" is not only your parents' surname, but also wish you beautiful. At the same time, you imply that you are Pisces.

Personally, I think what I explained here is quite meaningful. It is difficult for me to explain the allusion connotation of the word "sweet and clear" later, because I have studied Chinese and western cultures and ancient times. Let's just say that "sweetness" is the love of parents, and "affection" is an ancient courtesy title for people.
