Pressure cooker for half an hour? You're really great. If you press it for 20 minutes, the average little pig's feet will be crushed.

Press the meat first, and at the same time, put the mung bean in a pot and cook it slowly for 20 minutes.

Then cook the pressed meat with mung beans and cook it in a pressure cooker. This time is not urgent! Cooking. Open the lid and it will take 5 or 6 minutes.
