What are the records of woodpeckers in China?

Woodpeckers have made great contributions to the protection of trees. People call them "rangers" or "tree doctors". In some ancient books in China, there are long-standing records about woodpeckers pecking at wood and eating insects. For example, there is a record of "aiming at wood" in Bird Book, and there is a record of "eating moths through wood" in Foreign Material Book. Li Shizhen's Compendium of Materia Medica in Ming Dynasty pointed out: "This bird chops trees to get the name of moth". In addition, there are birds in Nanshan, whose name is pecking wood. Hunger pecks at trees and nests at dusk. People do nothing but do whatever they want, and those who are pure in nature are proud and those who are turbid are humiliated. "Tintin is anxious and thin at night, pecking around on the court and refusing to come back. I have been hurting you all day, so I don't think there is anything to fly. "Singing woodpeckers' poems shows that woodpeckers have been loved and praised by people since ancient times.
