Chinese New Year
There are some old customs that only a few people or even no one does any more. People still do their "spring cleaning" before the holiday but, in old China, they did not sweep or wash clothes on New Year's Day itself. They were afraid of cleaning away good luck together with the dirt. For the same reason, some people did not wash their hair and were very careful not to break any tools. The 5th or 6th day after New Year, when they cleaned and threw away or burned all the trash, was a day for "sending off" the God of Being Poor, one of the sons of Zhuanxu. Today, it's more common to clean things as they get dirty, like on other days. Few do anything special about the God of the Poor. In the same way, people near Beijing thought that it was unlucky to cook or steam food for the first 5 days of the New Year. They would cook all of their next week of food 2 days before it, so it was ready for the reunion meal. They would add yeast to their dumpling skins the day before that, on the 28th day of the 12th month. The skins would have enough time to be ready but not enough time to go bad. Today, people cook or eat out all through the week. It is easy to buy ready-made skins at supermarkets, keep their homemade skins fresh in fridges, or just buy all their dumplings from nearby shops and there is nothing special about the 28th day. On People's Day, the 7th day of the holiday, people used to wear special headbands and thought good weather meant good luck for everyone in the coming year. Everyone used it to count their age, even when it was not their birthday. None of that is common any more.
