The practice of ringing skin (skin belly):

1. Boil the pigskin in cold water, take it out, and clean the fat on the pigskin after cooling.

Wash the treated pigskin, cut it into small pieces, and control the moisture.

2. Put a small piece of pigskin on oiled paper and put it in a cool place to dry.

3. Collect completely dried pigskin for later use.

4. Put the oil in the pot. When the oil is cold, put the pigskin in and heat it slowly with slow fire. When the pigskin is fully triggered by oil, drain the controlled drying oil, cool it, put it on oil paper and collect it in a cool place.
