Who knows there are poems describing the miserable life of working people? thank you

There are some poems about working people in The Book of Songs, such as "Cutting Tan" in our Chinese textbook:

Kan Kan cut sandalwood, the river dried up, and the river was clear and rippling. No crops, no crops, no crops, no crops. No hunting, no hunting. Is there a county in Hu Zhaner's court? He is a gentleman, he is not a vegetarian!

Kan Kan is spreading, the river is flowing, and the river is clear and real. No crops, no crops, no crops, no crops, no crops. No hunting, no hunting, is there a special county in Hu Zhan's court? He is a gentleman, and he is not a vegetarian!

Kan Kan cut the wheel, the river flows, the river is clear, and the river is destroyed. No crops, no crops, no crops, no crops. No hunting, no hunting. Is there a county quail in Huzhanerting? He is a gentleman, but he is extraordinary!

There is also a famous song, selling charcoal Weng.

Bai Juyi

An old man selling charcoal cuts wood and burns charcoal in the mountains in the south all year round.

His face was covered with dust, which was the color of smoke burning, his temples were gray, and his ten fingers were burnt black.

What is the money for selling charcoal for? Buy clothes, buy food in your mouth.

Pity that he is wearing thin clothes, but he is worried that charcoal can't be sold, hoping it will be colder.

At night, it snowed a foot thick outside the city. Early in the morning, the old man drove a charcoal wheel to the market.

Cows are tired and people are hungry, but the sun has risen very high. They are resting in the mud outside the south gate of the market.

Who is that proud man riding on two horses? It was the eunuchs in the palace and eunuchs who did it.

The eunuch, with documents in his hand and the emperor's orders in his mouth, shouted at the petrified palace.

A load of charcoal, more than 1000 kilograms, eunuch attendants to drive away, the old man is helpless, but there is no way.

Half a horse's red yarn is a silk, which is filled with charcoal to the cow's head.

There are also Du Fu's "Three Officials" and "Three Farewells", which are the abbreviations of Xin 'an official, Tongguan official, Shi Haoguan, marriage farewell, resignation and homelessness. These six poems were written by Du Fu in a planned and arranged way in March, 759, the second year of Gan Yuan. In March of that year, 600,000 troops of the Tang Dynasty were defeated by Yecheng, and the national situation was very critical. In order to quickly replenish troops, the rulers implemented an unrestricted, unorganized and inhuman policy of the Royal Air Force. Du Fu witnessed these phenomena with his own eyes and wrote these six poems with contradictory and painful feelings. This war is different from the belligerence in Tianbao period, and it is an effort to save the country and survive. Therefore, Du Fu, while profoundly exposing the darkness of military service, cursed "the end of heaven and earth is ruthless" and at the same time had to support this kind of military service; He not only sympathized with the people's sufferings, but also had to comfort and encourage those immature "middle-aged men" to go to the front with tears. Under the unbearable cruel oppression of the people, the wife advised her husband and mother to send their children to the battlefield one after another, and some elderly women even gave their lives. While exposing the cruelty of the ruling class, Du Fu praised the broad masses of the people with infinite sympathy and gratitude. "Three Officials" and "Three Farewells" have different expressions. The so-called "three officials narrate with questions and answers, and three farewells are purely between the sender and the traveler." In Three Officials, Du Fu himself appeared because of the question and answer. In "Three Farewells", Du Fu did not appear, because the whole story is a monologue of the characters. From the literary origin, Three Officials and Three Farewells inherited the styles of The Book of Songs and Han Yuefu, inspired Bai Juyi's new Yuefu, and were the pinnacle of Du Fu's realistic creation.
