I think the most important thing about mala Tang is hygiene. The food in the shop will be better than that outside, but the cooking water will keep cooking. Boiling water for a long time will produce bad things. It is recommended to eat less mala Tang, so that you will not consider what calories are. You don't have to worry so much about the calories of everything in your life. You should eat normally and do more exercise, so that you won't get fat.
