"Dog" is a Chinese character, pronounced as (xiāo), which is a relatively seldom used word. Generally speaking, it only appears in literary works or poems. Its original meaning refers to monsters or gods in the mountains, often described as mountain spirits or forest spirits that look like people, and sometimes described as strange and mysterious creatures.
According to Shuo Wen Jie Zi, filial piety means "supernatural". The composition of this word is "ghost" and "Xiao", in which "ghost" means mysterious supernatural power and "Xiao" means image. Therefore, the meaning of the word "dog" can also be interpreted as a mysterious image or mysterious existence.
Raccoons are actually monsters in ancient mountains. After it was discovered by our ancient ancestors, our ancestors acted flexibly according to its characteristics and named it raccoon.
It is said that there is a kind of mandrill that lives in the mountains, so it is called mandrill. Mandrill is a monkey. It has a short tail, a blue face, a red nose, a white beard on its mouth, a dark brown body and a white abdomen. Live in groups; Now it seems to be what we call a monkey.
Because this kind of animal likes to live in groups and is savage by nature. Therefore, the ancient uniqueness is avoided, and sometimes the mandrill will make a harsh sound. Therefore, there is also a general record in the poem, and its voice is piercing, such as resentment. This sentence means that the sound of this animal is very sad. It's like telling your grievances, and it's like something unfortunate happened, which makes people get goose bumps.
