Good self-control. As you said, Zhang Xiaotian is now the new dean of Shengjia College.

Matters needing attention are mainly as follows:

1. Don't let the wound get wet with water for a short time. Proper application of some antibiotic ointment on the wound can prevent the wound from infection, while a small amount of blood and other secretions oozing from the wound can be gently wiped with sterile cotton swabs.

The wound won't bleed in about 2.3 hours. You can wash the scab accumulated in the wound with 3% hydrogen peroxide, then rinse it with normal saline, and apply antibiotic ointment appropriately to keep the wound dry.

3. The local swelling occurred 0-2 hours after operation and reached its peak in 24 hours. We can use cold compress to alleviate this phenomenon, which will gradually fade after a period of time and will not appear again, so don't worry.

4. Take a semi-recumbent rest mode, which is beneficial to blood circulation.
