You can't. The meat in the perfect Delibao wok will contain more bacteria and toxic substances produced by bacterial metabolism if it stays overnight. If meat is not stored properly overnight, it may affect the normal physiological function of human tissues and organs and disturb the balance of intestinal flora. For some people with bad stomachs, there may be symptoms of gastrointestinal discomfort such as abdominal pain and diarrhea. Therefore, you can't eat meat all night in the perfect Delibao wok.
