Camellia oleifera is quite healthy food. I go to a fixed store to drink Camellia oleifera almost every weekend. In Gongcheng, Ziyuan, Guanyang and other counties, local people can almost drink Camellia oleifera as three meals a day, which can warm the stomach and drive away the cold, which is very good for the stomach. It also has a curative effect on the early stage of cold. When drinking Camellia oleifera, it should be accompanied by some snacks, such as boat cake, wormwood cake, fried rice flour and so on. This kind of diet is a must for Guilin people to have a midnight snack.
