Does any literary expert know who Mr. Yao Zhen really is?

Meng Jiao, of course. The point is that you misunderstood the meaning of "privacy". It is very difficult for a bachelor of letters or a hermit to get posthumous title, but it is added by his relatives, friends, students or old collectors. This is called privacy. So this refers to Zhang's Meng Jiao and posthumous title.

Posthumous title is another title given by China in ancient times after the death of a ruler or a person with status, such as "Emperor Wu" and "Mourning for the Public". After the death of ancient emperors, governors, high officials and ministers, the imperial court gave them a title of praise or blame for good and evil according to their life behavior, which was called Shi or posthumous title.

The so-called "big line is famous, small line is famous." Do it for yourself, and you will be born in the world. "

Due to the limitation of hierarchy, posthumous title's requirements are very high:

Emperors of the Western and Eastern Zhou Dynasties, governors of various countries, doctors and wives of the Qing Dynasty all qualified as posthumous title.

According to the Han Dynasty, only those who were sealed before their death were qualified as posthumous title.

The Tang dynasty stipulated that professional officials should have more than three qualifications to be qualified;

Therefore, it is difficult for a bachelor of arts or a hermit to get a posthumous title, but it is added by his relatives, friends, students or old collectors, which is called a private appointment, which is different from that awarded by the court.
