It is not recommended to suture the wound by yourself without going through a professional doctor. Self-suturing may cause serious infections, poor healing, and obvious scars. There are many other problems, and there is a greater risk. If the wound is shallow, small and clean, it can be simply treated according to the following formal steps (but it is still not self-stitched)： 1. **Clean the wound**: Gently rinse the wound with saline or clear water to remove dirt and impurities. 2. **Disinfection**: Use disinfectants such as iodophor to disinfect the skin around the wound from the inside out. 3. **Bandage**: Cover the wound with clean gauze or band-aid, fix it properly, and keep the wound clean and dry. Once the wound is deep, large, obviously contaminated, bleeding, involving joints or important organs, etc., be sure to go to the hospital as soon as possible, and a professional doctor will perform debridement, suture and follow-up formal treatment to ensure the smooth healing of the wound and reduce complications.
