不能则学，不知则问 (bù néng zé xué, bù zhī zé wèn)

不能则学，不知则问

(bù néng zé xué, bù zhī zé wèn)
English Translation:“If you can’t, learn; if you don’t know, ask.”

Meaning:
If you don’t know how to do something, you should study it until you do. If you don’t know something, be humble and ask others for help.

Example:
你遇到困难时，记得不能则学，不知则问。
(When you encounter difficulties, remember: “if you can’t, learn; if you don’t know, ask.”)a
