Another polite term that is easy to remember and use.Very Good. Hen Hao.This is useful when giving praise for a job or task well done. Also useful as a reply to anyone who says "Ni Hao Ma?' to you.

Ni Hao Ma? (How are you?)
Hen Hao (Very Good)No Good Bu Hao.

This is useful when there is a need to comment on a shoddy or incomplete job or task. Can also be used as a reply to Ni Hao Ma? but may not be such a good reply.

Ni Hao Ma? (How are you?)
Bu Hao (No Good)
