The method of scaling is as follows:

1. First rinse the slaughtered sturgeon in water, and then scald the sturgeon skin with boiling water of about 80 degrees.

2. Sprinkle some salt and white vinegar on the sturgeon, be careful not to use too much, just enough.

3. Next, use a knife, bamboo skewer, clean steel wire ball for washing pots, etc. to scrape slowly.
