It is a very important concept in China traditional culture, which may affect people's life and work. The idea that these taboos have a bad influence on some things is often regarded as a religious belief, which is widely circulated and observed. On this day, people often avoid building or moving at home, and there are no important ceremonies, such as getting married. In rural areas, people even avoid cooking in the kitchen on this day to avoid taboos.
Although more and more people in modern society have given up these folk beliefs, the traditional culture and rural areas of China are still widely observed. Although it may be regarded as superstition, in these areas, observing these taboos is also a kind of cultural common sense. So, if you don't want to be jealous, you'd better pay attention to the calendars in the market and online, and then avoid making any important decisions these days. This can avoid embarrassing things on some anniversaries or festivals.
