Most sour lemons are produced in Anyue County, Sichuan Province, the hometown of lemons in China, but they are also planted in other places such as Yunnan, Taiwan Province and Hainan. But everyone should separate the producing areas of sweet lemon and sour lemon. Sweet lemon is the fruit planted by Sichuan Academy of Agricultural Sciences. At present, only Sichuan and Chongqing have relatively small planting areas and are not common. Babies who want to taste sweet lemon can try Muyami sweet lemon. At present, it is the only brand of sweet lemon I have ever eaten.
