What are the five categories of Confucian businessmen in Jinan?

The first introspection (courtesy), if you have any questions, look at yourself. It is the concept that makes everything.

The second kind of altruism (righteousness) is to give whatever you want.

The third breakthrough (intelligence) is to do what you are afraid of and do what you do.

The fourth proof (benevolence) is that there are ideals to prove that all kinds of seeds are great love.

Fifth, honesty (trust) and zero tolerance for dishonesty are unconditional.
