I repair cars. My master will celebrate his birthday tomorrow. Do you have any wishes?

Once a teacher, always a father! I will study your exquisite skills hard in the future and add luster to you! 、

It is this kind of expression of determination or something, and finally wish him a happy birthday.

Master usually likes to hear students say that he is good at technology and will learn from him with an open mind. It's probably just a courtesy.
