Hainan betel nut ancient books

Betel nut flowed into China in the Western Han Dynasty. In the first year of Yuanfeng (1 10 BC), there were nine counties including Hainan and Vietnam. Betel nut appeared in Chang 'an as a tribute, so it first appeared in Shangfulin, Sima Xiangru. He wrote: "Leave it redundant, and benevolence is frequent"; Renpin (frequency sound object) is the betel nut tree mentioned today, which is a palm tree. This image, in Zuo Si's Five Degrees of Fu, developed into: "Betel nut has no ke, coconut leaf has no yin". The widespread popularity of betel nut in the Southern and Northern Dynasties originated from this. At the same time, we can find many records about betel nut in a small country in the South China Sea from the history books.
