The purpose of Tomb-Sweeping Day activities.

Tomb-Sweeping Day is a traditional major Spring Festival. It is a fine tradition of the Chinese nation since ancient times to sweep graves and remember our ancestors. It is not only conducive to promoting filial piety, awakening family memories, but also conducive to promoting the cohesion and identity of family members and even the nation. Tomb-Sweeping Day's integration of natural solar terms and humanistic customs is a combination of humanistic and natural conditions, which fully embodies the Chinese ancestors' pursuit of harmony between heaven, earth and people, pays attention to conforming to the right time, place and people, and follows the laws of nature.

Tomb-Sweeping Day, also known as outing festival, outing festival, March festival, ancestor worship festival, etc. It was celebrated at the turn of mid-spring and late spring. Tomb-Sweeping Day is the biggest ancestor worship festival of the Chinese nation, which originated from ancestors' beliefs and customs of worshipping spring. Tomb-Sweeping Day has two connotations of nature and humanity, which are both natural solar terms and traditional festivals. Grave-sweeping and ancestor-worship outing are two major themes of Tomb-Sweeping Day, which have been passed down since ancient times in China.
