Like father, like son.

This phrase suggests that the son is fantastic because of his father.
People can find it in New English-Chinese Dictionary.

A few days ago, I re-united with some old fellows. One guy has a very beautiful daughter. In particular, her eyes are so big and bright. Of course, all of us needed to flatter this guy. What I said is: "Like mother, like daughter." I am still delighted for my flattering.

If somebody says Ji-Ang's son(duaghter?) is so smart, I would follow hiim by saying "Like father, like son."
