Hugu Lake, located at the junction of Yanyuan County in Sichuan and ninglang county in Yunnan, is a plateau lake with clear water and beautiful scenery. The Mosuo people living by the lake still retain the "matriarchal family" lifestyle, and are called "living fossils" to study the development of human history. Mosuo people are very good at food, and their "pork belly" is unique.

"Pork pork" is smoked with the whole pig. The specific production method is as follows: the slaughtered fat pig is unhairing, eviscerating and boneless. In order to maintain the integrity of the pig head, the skull is not removed. If the pig has a lot of lean meat, it is necessary to remove some lean meat. When the water on the pork surface is slightly dry, put some spices such as salt and pepper powder and wipe them evenly by hand. Then sew the cut part of the pigskin with needle and thread to keep the shape of the whole pig. Finally, the pine branches or cypress branches are smoked into golden yellow, thus making "pork belly". "Pork pork" is transparent, colorful, delicious and has a unique fragrance. If the whole pig is preserved, it can be stored locally for several years without deterioration. In addition to eating, pork belly is also a necessary item for Mosuo children 13 years old to hold adult ceremonies. Adult ceremony requires children to stand on it, so every Mosuo family will make "pork belly".
