Bacon is a kind of bacon in China, which is mainly popular in Sichuan, Hunan and Guangdong, but it is also made in other parts of the south. Because it is generally preserved in the twelfth lunar month, it is called "bacon". Bacon has the characteristics of constant meat quality, long fragrance and long storage from the processing, production and storage of fresh meat. Because this kind of meat is smoked by cypress branches, it is not afraid of mosquitoes and flies in summer and does not go bad for three days. It is a unique local flavor food.
