During the Tang Dynasty, the big one-horned rhino was distributed in two lakes, Guangdong, Yunnan and Guizhou, and even QH. During the Ming Dynasty, it was only distributed in Yunnan and Guizhou, and during the Qing Dynasty, it was only found in YN areas.

By the beginning of the 20th century, the large one-horned rhino was completely extinct!

This reason is because rhinos have too high environmental requirements, especially for large one-horned rhinos. The gradual cooling of the climate is one of the very important factors. Rhinos are an animal that likes warm climates. Around 500 BC, the climate north of the Yellow River began to significantly cool down, and the rhino population in the region continued to migrate southward. By the Tang Dynasty, the area north of the Yellow River was completely unsuitable for rhinos to survive.

During the Zhenyuan period of Tang Dynasty, a large one-horned rhino was hunted for thousands of hardships and sent to the palace. As a result, in winter, the rhino froze to death in the Chang'an Palace Zoo because of a snowfall.

Population pressure is also a very important factor. After the number of humans exceeds a certain range, they will inevitably burn mountains, forests, swamps, and reclamation of hills and lakes, permanently destroy their living environment and occupy their habitat on a large scale.

Under the combined action of climate and population pressure, the living space of the large one-horned rhino was permanently destroyed, and regional extinction occurred. Because the maximum population pressure that the large one-horned rhino can withstand can only have four humans per square kilometer.

Anyway, the big one-horned rhino is finally extinct.
