When Bao Zheng was an official in Duanzhou in the Song Dynasty, he wrote a poem "Book on the Zhaibi of Duanzhou County" as follows:

Purifying the heart is the root of the cure, (purifying the selfish mind is the root of the cure) Fundamental)

The straight path is physical strategy. (Speaking the straight way is the purpose of establishing oneself)

Good work will eventually make a building, (good wood will eventually become a pillar)

Fine steel does not make hooks. (Good steel is strong and unyielding)

The rats and birds in the warehouse are happy, (the rats and birds in the warehouses are happy when there are many grains in them and steal the public grains)

The rabbit and the fox are sad when the grass is exhausted. (There are no weeds in the wild, and rabbits and foxes who often nibble on green grass are worried)

The sages have left instructions, (remember the teachings left by the sages on how to behave)

Don't bring shame to those who come. (Never let future generations feel ashamed when they think of me)

Obviously, this is a piece of work that expresses feelings and expresses one's aspirations.
