A researcher majoring in folklore in Chinese Department of Peking University said that there was no such saying in ancient times. She thought it was a very rustic remark. For example, in some areas of Shandong, there may be a custom of "not worshipping on weekends", fearing that someone will die, and going to worship again every two months will bring another death.
With the popularity of the Internet, the customs in many places have been magnified, and people pay special attention to it, with a curiosity, but there is no scientific basis and no history. Don't worry about whether Tomb-Sweeping Day can visit the grave, but it doesn't matter. Tomb-Sweeping Day is a day of sacrifice and grave-sweeping. Remembering our ancestors and inheriting filial piety is the most important thing to do. We can't lose the tradition of our ancestors just because of the leap month.
The development and evolution of Tomb-Sweeping Day;
Tomb-Sweeping Day is the Spring Festival of the Chinese nation, and the Spring Festival in Tomb-Sweeping Day corresponds to the Autumn Festival of Chongyang and the Spring Festival in Spring and Autumn, which has existed since ancient times. Tomb-Sweeping Day has a long history, which changes with the development of the times. Later, it gradually merged the customs of Cold Food Festival and Shangsi Festival. In ancient times, the north and south of China had different customs. Before the Tang Dynasty, grave sweeping in northern China was mainly held in Cold Food Festival and Cold Clothes Festival.
Tomb-Sweeping Day combined two holiday customs, cold food and thinking above, and in the Song and Yuan Dynasties, it formed a mode centering on ancestor worship and grave sweeping, and combining the custom of forbidding cold food with the custom of thinking above outing. With the custom of forbidding fire and eating cold food in the Cold Food Festival moved to Tomb-Sweeping Day, some places in northern China still retain the habit of forbidding fire and eating cold food in Tomb-Sweeping Day.
