1, rawhide, pigskin and pork, also known as Fengxiaosheng, Dali, Yunnan, Bai Haige and Nanzhao (738 -937), were popular in Dali and Eryuan, and Japanese media called Dali rawhide "pork sashimi".

2. In Dali area, when Bai people kill pigs, they burn pig skins with straw to remove hair, and a pig is killed. They cover the pig skin with straw, wheat straw or pine wool, set fire to it, roast it several times until the whole pig is burnt black, shave off the pig hair, suffocate it with ashes at last, about 1 hour, and then rinse it with hot spring water. The burnt pigskin is golden in color and fragrant. At this time, the skin has been burned through but not cracked, and the part two or three inches below the pigskin is cooked. Then dissect the abdomen, and cut the "invisible part (belly bottom meat, hind leg meat)", pig mouth and pig liver into thin slices or filaments while fresh.
