Soak zongzi leaves in cold water for 2-3 hours, and then cook them directly in cold water for 4-5 minutes, provided that they are boiled in cold water for 5 minutes, and then they can be wrapped after being picked up.
If you cook in a pressure cooker, it will take about an hour. If you use a pressure cooker to boil, you can cover the pressure valve when the steam in the pot starts to come out, and then turn to a low heat. Boil for 30 minutes, then turn off the heat and stew for 20 minutes. If you cook zongzi in an ordinary soup pot, it will take three hours for the water in the pot to boil.

Precautions:
When wrapping zongzi, don't put too much rice, because the rice inside will swell when cooked, and it will easily break the leaves of zongzi if you put too much rice. If it feels similar, you can take it out and have a look. If it is not cooked, you can continue to cook it in the pot.
But when cooking zongzi, don't wait for it to cool before putting it back in the pot, which will affect the taste. After cooking zongzi, don't rush out of the pot, let him soak in the pot for an hour first, so that the cooked zongzi will taste more delicious.
