What do you mean by humble in Han and Tang Dynasties?

This should be a conative usage, that is, what to consider ... ugly (rough, ugly, etc. ).

One of the sources of humble Han and Tang Dynasties is Lu You's Self-mockery in Song Dynasty. The full text is as follows:

Read less poetry books, poor Han and Tang dynasties, and send your life to agriculture and mulberry.

Riding a donkey wants to land on his feet, and there is always a bottle of wine around him.

Old to describe, although changed, drunk in high spirits.

What does the Taihang Wangs do? It's like laughing at the foolish old man's overreaching.

When I was a teenager, I read poetry books and didn't even care about Han and Tang martial arts. Send yourself to farm mulberry when you are old.

Riding a donkey, his feet are about to touch the ground, he likes to drink, and his glass is always on his side.

Although his appearance has changed in his old age, he is still in high spirits when he is drunk.

How on earth did the two mountains of King Wu of Taihang move? Ironically, I don't measure myself like a stupid old man.
