What is the basis for the production of small minister rhinoceros bottles?

The production time of Chen Xiaoxi's ox bottle is about between the first and Di Xin. According to research, the climate of the Yellow River and Yangtze River basins in ancient China was warm and humid, and rhinoceros and other large creatures living in tropical and subtropical areas were widely distributed at that time.

According to my little official rhinoceros bottle, people in Shang dynasty saw rhinoceros, otherwise it would be impossible to create such realistic works. Moreover, the discovery of paleontology also confirmed this. Rhinoceros bones have been found in Yinxu in Anyang, Hemudu in Zhejiang, Nanning in Guangxi and Xiawanggang in Xichuan, Henan. In addition, the "Xi" in Oracle Bone Inscriptions of Shang Dynasty is a rhinoceros. By the Eastern Zhou Dynasty, there were still a large number of rhinos in the Yangtze River basin.
