Don't pretend to understand(bu yao zuo bu dong zhuang dong de ren )

In front of the public, we should have a low-key attitude, a humble tone, a down-to-earth style, and an honest character, instead of showing and showing off ourselves in ignorance. For what we really don't know, we should show our ignorance modestly and with a smile on our face; for what we only know, the best way is to be silent, listen and learn.

If you know everything, the result is that you don't know anything and it's easy to lose the trust of others.
