知子莫若父 can be translated as “No one knows a son better than his father.”

This idiom is based on the idea that after spending many years together, family members know everything about each other. Better than anyone else, a father knows the qualities and shortcomings of his son.

If you are looking for something about “father and son,” this is probably the best selection.

While this is the original proverb (very old), others have been composed about various combinations of mothers, sons, daughters, and fathers. Let me know if you need a custom version.

This Kanji represents a bond, as in the bond between mother and daughter, father and son, family ties, or a family bond.

絆 is the kind of character that says, no matter what happens (difficult times), we have this bond that cannot be broken.

If you go to the Japanese dictionary, the definition is the bonds (between people), (emotional) ties, relationship, connection, link, tether, or fetters.

This Kanji is best if your audience is Japanese. While this is also a Chinese character, it has a completely different meaning in Chinese (it means to hinder or stumble in Chinese). it’s a very rare character in Korean Hanja but does mean bond in Korean (used in Korean words for certain kinds of glue and sticking plaster).
