It was 1800 years ago that Sun Quan gave Cao an elephant. The reason why Sun Quan sent elephants to Cao Cao was mainly because Cao Cao was powerful at that time and Sun Quan had little power. Sun Quan's sending animals is also a diplomatic means. Because ancient people worshipped some rare birds and animals, and thought that rare birds and animals could bring safe luck to the country, small countries with barbarian land often sent local unique animal species to the Central Plains, and there were special people to support them in the royal gardens.
