Anti-symbol to symbolize: imitate the meaning of something, but use opposite things to prove it. The whole sentence is "reverse symbol to symbolize". In layman's terms, "ge" as a noun is usually taken as It means the skin of an animal being skinned off, but later as a verb, it means transformation or change. The leather of beasts is tough and difficult to change, which symbolizes that things are firm and not easy to change, which shows that it is difficult to return to the past, customs are difficult to change, and the act of reforming the past is very difficult. However, we use the word "leather" to refer to "change", which corresponds to the toughness and difficulty of change that was previously referred to as "animal skin". Using "hard-to-change" things as the "name of change", image and consciousness seems out of place. In fact, this is not uncommon. We usually call this approach "reflecting symbols to symbolize". This is my understanding, purely hand-made, I hope it can solve your doubts.
