Boil the water, add the dumplings, change the "strong fire" to boil as quickly as possible to avoid sticking to the bottom of the pot, and push the dumplings gently with a spoon.
If the water is boiling very hard, you need to add a little cold water to "light" it to avoid boiling the dumplings. Generally, light it 3 times, then turn it off again, take it out and put it on a plate.
About 7 or 8 minutes.
Cook it a few times and as you gain experience, enjoy the food to the fullest.
