Xiaomi spicy stew is a traditional Sichuan dish. Usually, pork is cut into large pieces and then stewed. There are several reasons for cutting pork pieces:

1. Easy to taste: Cutting pork into blocks can increase the contact area between the surface of the meat block and the seasoning, which is beneficial to the penetration and taste of the seasoning.

2. The cooking time is more uniform: the pork cut into pieces is heated more evenly during the stewing process, the cooking time is more consistent, and the meat quality is tender.

3. Convenient entrance: Chopped pork is easier to enter and more convenient to eat.

Of course, whether you need to cut pork slices depends on your personal preferences and cooking habits. If you like the whole pork, you don't have to cut it, but it should be noted that the cooking time may need to be adjusted accordingly to ensure that the pork can be stewed thoroughly.

The best way is to decide whether to cut pork pieces according to your own taste and cooking needs. If you are not sure, you can refer to relevant recipes or consult someone with cooking experience.
