Beast:
With the development of society, the word "beast" is gradually used as a noun. So people invented a new word "hunting" to mean hunting. Animals also have a special usage, that is, they refer to tigers alone. For example, "animal mouth" is "tiger mouth" This is because in the Tang Dynasty, people often changed the word "tiger" into the word "beast" in order to avoid Li Hu, the grandfather of Tang Gaozu Li Yuan.
According to research, as early as the beginning of the Zhou Dynasty, when Xiaoding Yu came into being, there was already a simplified word with only "hey" and no dog. In the following ancient prose, the words "hey" and "beast" are universal. Their pronunciation and meaning are exactly the same. It was not until the Han Dynasty that the word "hey" was abandoned.

According to textual research, this writing method was first seen in calligraphy works such as running script and cursive script in the Jin and Tang Dynasties, and was gradually recognized and passed down. Oracle Bone Inscriptions, the word animal, tells us a historical fact. In the Oracle bones era or earlier, people have tamed dogs as hunting assistants.
