If it is too late to eat, wrap it in plastic wrap and put it in the refrigerator to prevent deterioration. Because there is no preservative, it can be stored for up to 3 days. When storing, as long as the mouth of the fresh-keeping bag is tied tightly, the storage time should not be too long. When taking it out, put it in a steamer and steam it, so that the skin will not be hard.
The origin of the Youth League:
Dayu (22nd century BC) was in charge of water conservancy for thirteen years, and there was no one at home. He dredged the three rivers into the sea, and the water level in Taihu Lake dropped, which calmed the flood and created conditions for planting winter wheat, and won the love of Suzhou people. Today, there are many stories about Dayu's water control in Taihu Lake Basin.
According to legend, there was a young man in Suzhou who saw people from Tomb-Sweeping Day offer a beautiful sacrifice to Dayu. He thinks that this is not worthy of Dayu's frugality before his death. He thinks that Dayu must be uneasy under the grave.
It is time for winter wheat to turn green in Tomb-Sweeping Day. He discussed with everyone how to make a green jiaozi with wheat leaf juice and glutinous rice flour, and enshrined it in front of Dayu's tombstone for water control, not forgetting Dayu's kindness in water control. Over time, imitating each other has become a custom. Suzhou people still use green glutinous rice balls as offerings when they go to the grave in Tomb-Sweeping Day. If the green dumplings are made of wild oat leaf juice and glutinous rice flour, it will be even more fragrant.
