The "Classic of Mountains and Seas" Records that the Nanshan Classic records that five hundred miles to the east, the mountain of prayer, there is more gold and jade on it, and there are many rhinoceros and elephants under it. It means that five hundred miles to the east, there is a prayer over the mountain, the mountain is rich in gold and jade, there are many rhinos under the mountain, and there are elephants, rhinos and elephants that we are very common.

But what kind of animal is this "wolf"? The "Classic of Mountains and Seas" Hai Nei Nan Jing describes the shape of the wu on the line, the shape of the hu in the east of Shun, the south of Xiangshui, its shape is like an ox, black, a horn, which means to be on the east side of the burial ground of The Emperor Shun, on the south bank of the Xiangshui, the shape of the hu is like an ox, the whole body is blue-black, and it has a horn.
From the above two records, it can be seen that the goo is definitely not a cow, nor is it a rhinoceros, otherwise why use the three words of cow, rhinoceros and 兕 to describe it, the "Commentary" says that the goo is an animal with a horn that looks like a bison, cyan, thick skin, and can be armored. In Chinese myths and legends, the golem is a kind of ancient beast, the mount of Taishang Laojun is the golem, the "Chinese" also records that Wu Wangfucha had 103,000 soldiers wearing armor, and the "Record of Kao Gong" believes that the skin is tougher than the rhinoceros skin and can be put for an extra hundred years, so in ancient times people often hunted and killed the goat and used its skin to make armor.
It is not a rhinoceros but resembles a rhinoceros, and its skin is very thick, which is very similar to the extinct prehistoric animal Thunder beast, an extinct mammal in the order Strange-hoofed, which lived in North America 56 million to 34 million years ago.
Rhinoceros has a long and a short two sharp horns, and the thunder beast has a forked horn, the shape of this horn is very similar to the word, we know that the Chinese character is a hieroglyph, is it possible that the ancients saw the thunder beast, and then created the word according to the shape of the horn?
