History of botany

Pomelo and orange were both found in China's written records in the 3rd to 4th century BC. At that time, oranges and pomelos were planted along the Yangtze River, and both of them were selected as tributes. However, whether the pomelo recorded in ancient books in China belongs to the same plant as the pomelo now called is controversial. Tanaka Kozaburo inferred that the pomelo called in ancient China was the orange, not the pomelo that was used to be called later, based on the fact that some ancient Japanese books and Japanese folks called it Yuzu. Yu in Japanese is homophonic with grapefruit in Chinese, and Yuzu is grapefruit in Chinese.

In fact, Chinese pomelo is pomelo, and Japanese Yuzu is orange called by Japanese people, which is different. It is unscientific and putting the cart before the horse to insist that the pomelo pointed by China people is called the orange by the Japanese just because the two are homonyms. The cultural exchange between China and Japan began in Qin and Han Dynasties and flourished in Han and Tang Dynasties. However, pomelo has been recorded in ancient books in China before the Qin and Han Dynasties (see works Han Feizi and Lu Chunqiu in the 3rd century BC). That is to say, pomelo is ahead of orange.
