Let's talk about the first one first

There is no class in teaching. This is the 15th Analects of Wei Linggong by Confucius. Confucius said, "There are no classes in teaching."

It means that some people should not be excluded from education because of wealth, nobility, ignorance, good and evil, etc. This is the characteristic of Confucius' civilian education, which changed the privilege of being educated by nobles before.

Everything depends on Wen Cheng.

This is the characteristic of the imperial examination in Song Dynasty, when Neo-Confucianism rose. Cheng refers to Cheng Hao and Cheng Yi.

Lu You wrote in Volume 5 of Notes on the Old Xuegong: "Scholars in this dynasty ... everything depends on Wen Cheng."

Only those who are really talented are recommended.

It was Cao Cao's idea of employing people during the Three Kingdoms period.

Cao Cao's "Seeking Talents": "The second son and the third son help me humble, which is the only one, and I can use it." Cao Cao chose people who "let bygones be bygones", such as Zhang Liao; "Do your best" such as Ren Jun; Good at selecting talents in practice, such as Guo Jia.

The word fair competition is too hard to say.

Which dynasty can truly achieve fair competition?

However, the imperial examinations in the Tang Dynasty had an "open examination system".

How to say this question is obviously wrong.
