The scientific name of "pot vegetable" in Chaoshan dialect is "glass lettuce" (Lactuca sativa), also called leaf lettuce, which is a plant of the genus Lactuca of the Asteraceae family.

Glass lettuce is used to be used as a vegetable in hot pot, so it is called pot dish.

Besides, what I said upstairs: lettuce, coriander, watercress, coriander, cabbage buds, cabbage, etc., are not "pot dishes". If you are not from Chaoshan, please don’t mislead me.
