What is both a festival and a solar term? Brief introduction of festivals and solar terms.

2. Tomb-Sweeping Day, also known as outing festival, outing festival, March festival and ancestor worship festival, is celebrated at the turn of mid-spring and late spring. Tomb-Sweeping Day originated from the ancestral belief and the custom of worshipping spring in ancient times, which has both natural and humanistic connotations. It is both a natural solar term and a traditional festival. Grave-sweeping and outing are the two major themes of Tomb-Sweeping Day etiquette and customs, and these two traditional themes have been passed down from ancient times to the present in China. Tomb-Sweeping Day is an ancient festival of the Chinese nation. It is not only a solemn festival to pay homage to ancestors, but also a happy festival for people to get close to nature, have an outing and enjoy the fun of spring.

3. Winter solstice, also known as solstice, winter festival and Asian New Year, has dual connotations of nature and humanity. It is not only an important solar term among the 24 solar terms, but also a traditional folk ancestor worship festival in China. The solstice in winter is one of the eight festivals in four seasons, and it is considered as a big holiday in winter. In ancient times, there was a saying that the winter solstice was as big as a year. The custom of winter solstice varies in content or details due to different regions. In southern China, there are customs of offering sacrifices to ancestors and enjoying the winter solstice. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.
