Slices of meat can be cooked in boiling water for about 3 minutes; they are tender and easy to cook. Cooking it too long will make the meat cook old and taste bad. If the meat is cooked old, you can add tea leaves, tangerine peel and other seasonings to make the meat more crispy. Boiled sliced pork is a local dish originated in Zigong, which is a famous home-style dish in Sichuan cuisine. It doesn't take too long to cook, just cook it a little bit and then you can take it out of the pot.
