4. Do not use a casserole to cook food that is too sticky.

5. Do not burn it dry, and do not wash it with water when it is still very hot, as this may cause cracking.

6. Do not wet the bottom of the pot. When washing the pot, try not to wet the bottom of the pot, and make sure the bottom of the pot is dry when cooking. Before each use, wipe away any water from the outside of the casserole.

7. If you feel that the smell is easy to retain in the pot, you can try adding hot water to the casserole and adding tea leaves to cook.

8. Casserole that has been used to stew Chinese medicine should not be used to stew or boil soup. Similarly, any casserole used to stew or boil food should not be used to fry Chinese medicine.
