Sour lemons are mostly produced in Anyue County, Sichuan Province, the hometown of Chinese lemons, but they are also grown in other places such as Yunnan, Taiwan and Hainan. But everyone needs to distinguish the production areas of sweet lemons and sour lemons. Sweet lemons are the result of planting by the Sichuan Academy of Agricultural Sciences. Currently, only Sichuan and Chongqing have relatively small planting areas, which is not very common. Those who want to taste sweet lemon can look for Muyami Sweet Lemon. Currently, it is the only sweet lemon brand I have ever tasted.
