Japanese Tomb-Sweeping Day custom contains rich cultural connotations.

Tomb-Sweeping Day has a history of more than 2,500 years, and the connotation of festivals is also very rich. In addition to sweeping graves to worship ancestors, there are other colorful customs, and there are also different customs in different places in terms of diet. Tomb-Sweeping Day originated from the Cold Food Festival in ancient times, and it is said that it was established by Zhong Er, Jin Wengong, in the Spring and Autumn Period to commemorate his official Jiexiu. There is a saying that the cold food festival does not raise fire. Therefore, although there is no uniform diet custom in Tomb-Sweeping Day, the food in all parts of the country is mainly cool.

In the old store in Daoxiang Village, Beijing, the reporter saw that dumplings, sacrificial cakes "four products of flower rhyme" and stepping fruit had been put on the counter. Among them, the "Flower Rhyme Four Products", a sacrificial pastry with Beijing characteristics, is filled with sweet-scented osmanthus, saffron, roses and chrysanthemums, which not only expresses people's love for the deceased, but also expresses people's good wishes for a long and auspicious life for their loved ones around them. In some places, on the first night in Tomb-Sweeping Day, eggs and duck eggs are cooked, dyed blue and yellow, and carved into pictures on eggshells as cold food gifts.

In order to prevent cold food and cold meals from harming people's health, apart from sweeping graves, Qingming also carried out a series of folk sports activities, such as mountaineering, swinging, cuju, playing polo, inserting willows and flying kites, in order to let everyone exercise together. Some of these sports activities also contain people's beautiful sustenance for life.

Sacrifice and grave-sweeping are the themes of Tomb-Sweeping Day. Because most cemeteries are in the suburbs, the process of sweeping graves is not only a ceremony for family reunion, but also a good opportunity to feel the spring in the suburbs. Therefore, Tomb-Sweeping Day, a festival with rich cultural connotations, has both sad tears in memory of old friends and laughter for an outing.
