As the name implies, "closing the door" means setting off firecrackers when closing the door. Of course, the guns here are by no means military weapons, but the custom of setting off firecrackers in Wenzhou. In the past, most of the New Year's Eve banquets in Wenzhou were held (and they were all held at home). After the whole family eats the Lunar New Year's Eve drinks, all the things left outside the door should be moved to the bottom of the house for the New Year (even the broom is no exception), which means that Feng Shui is not allowed to flow out. Then set off firecrackers when you are ready to close the door. Every firecracker should hear the sound of double sound (double happiness), and it should be fired three times in a row (three Yang Kai Tai) and one * * * six times (66 Dashun). If a firecracker only makes one sound, immediately put a double tone to make up seven sounds (making a fortune). However, after the closing of the door, you can't open the door or go out tonight, otherwise the feng shui will escape. Opening the door is the morning of the second day (the first day of the first month). The whole family gets up and opens the middle door wide to welcome the first light of the new year (that is, opening the door). The same three shots reach six sounds. However, in recent years, on New Year's Eve, more than half of the people in China watched the live CCTV Spring Festival Gala program at home, so the "closing gun" was put on later and later, while the "opening gun" was put at 0: 00, meaning "closing the door at the latest, keeping the geomantic omen" and "opening the door at the earliest, or traveling far away". I remember there was a folk monthly meeting in Wenzhou about the activities of the first month.
