the use of fire in western food is relatively low. Generally, it is made by electricity, and the ambient temperature is relatively low. In addition, the taste pursues the original flavor, and there are not many flavors that need to be prepared.

Chinese food, on the other hand, has a high demand for fire. Basically, all dishes can't be processed without fire, and the chef needs to taste the seasoning, so wearing a mask will not be so convenient.
