1. soak the beef in cold water for about half an hour before cutting it into small pieces (I cut it very small and save it for beef noodles later).

2. Cut the onion and slice the ginger for later use.

3. Put the beef into the pressure cooker and add cold water (the amount of water should not exceed that of beef).

4, the fire is boiled, and the floating foam is removed.

5. Add onion, ginger, soy sauce and salt.

6. Cover and simmer for 20 minutes after the fire expands.
