2, change a pot of water, pour the ribs in and continue to cook (the water here must also be boiled water), do not add spices such as salt, you can add ginger, you can add a few drops of vinegar (so the stewed ribs are easy to stew in soup).
3, after boiling, simmer 1 hour (as bad as the pressure cooker).
4. After the ribs are stewed, add seasonings such as monosodium glutamate and salt.
