Floating the soup dumplings is a sign that they are cooked, generally speaking, it means they are cooked and ready to eat. Considering that different people have different palates, if you want the dumplings to be more flavorful, you can add cold water once and just float them again. This cycle is usually about 2 minutes.

Note: After the dumplings are cooked in the pot until they float, they should be quickly switched to a gentle fire, at which point, if they are still cooked with a high fire, the dumplings will rupture if they keep tumbling. If the dumplings constantly turning, uneven heat, but also easy to cook outside the hard inside is not good. Each open should be added to the appropriate amount of cold water, so that it seems to keep rolling non-rolling state, boil two or three times, and then cook for a while, you can fish out to eat.
