After the materials are prepared, it is the work of carving. Craftsmen need to have superb skills, be meticulous in heart and steady in hand. First outline the prototype, according to the charm of the form of the twenty-one finches, with a knife as a pen, lightly draw the outline on the material, or fly, or perch, or peck, or care, the posture is different, and it is wonderful to be lifelike.

"Tiangong Kaiwu" has a saying: "On the seven feelings of the world, it is said that happiness, anger, sorrow, and love evil desires. Husband's happiness, anger, and sorrow are born from the movement of love; love and evil desires are born from the change of love. As for the nine orifices of the bones, each has its own division, and there is nothing but the residence of love." Today's discussion of the impact of twenty-one chickens on the environment should be studied in detail to make it clear.
Twenty-one chickens are in one place, and their sound is disturbing. The sound of the chirping of chickens wakes people up in the morning, but if it is quiet, the flock of chickens chirps in unison, and the noise is so loud that the ears cannot be at ease. Gu Yun: "The cicadas are noisy in the forest, and the birds chirping in the mountains are more quiet." However, the chirping of chickens is not the
Furthermore, the filth of chicken manure also has an impact on the environment. Where chickens live, the filth accumulates, and if it is not cleaned up in time, it will stink to the sky. "Kaogong Ji" says: "Sometimes in the sky, there is gas in the earth, the materials are beautiful, and the work is clever. All these four can be regarded as good." The air of the environment is related to people's daily life, the air of chicken manure, and the freshness of bad air, which is not good for people's breathing.
And the activities of chickens often cause dust to fly. They dig for food in courtyards and open spaces, and the dust rises, causing the surrounding things to be dusty. The ancients said: "If you don't sweep a house, how can you sweep the world?" The movement of chickens, although not intentional, causes chaos in the environment and hinders cleanliness.
However, chickens are not completely beneficial. Chickens can eat insects and ants, and protect gardens and fruits and vegetables. "Qi Min Yao Shu" records the matter of farmers and mulberries, and also talks about the function of chickens. If insects and ants harm, chickens eat them, and fruits and vegetables will suffer less, which is beneficial to the balance of ecology.
Twenty-one Chickens in the environment have both the disadvantages of disturbing people, pollution, and chaos, and the advantages of eating insects and protecting gardens.
