I come from Inner Mongolia. I use lard for cooking, but I see that people in Liaoning are vegetarian. Why? Can't eat lard?
Eating habits vary from place to place. But generally speaking, lard is rich in animal fat, and eating too much is not good for your health, not as healthy as vegetable oil. In the past, life was hard and material was tight, so eating lard was no problem. Now that life is good and material is rich, it is better to eat vegetable oil.
