Some people directly skin quails alive when they kill them, which is quite cruel, but why skin quails alive?

It's troublesome to skin quail alive (quail has less blood, so it won't smell like blood when you eat it, which will make you sick).

Medical circles believe that quail is rich in egg phosphorus, which can produce lysophosphatide, inhibit platelet aggregation, prevent thrombosis, protect blood vessel wall and prevent arteriosclerosis. Phospholipid is an indispensable nutrient in higher nervous activity, which has the function of strengthening the brain.
