What solar terms are you thinking about?

Ghost Festival, Death Festival, Cold Food Festival and Ghost Festival, among which Ghost Festival, Ghost Festival and Cold Food Festival are not nicknames of Tomb-Sweeping Day.

The Cold Food Festival was originally to commemorate Jin Wengong's courtiers and mesons in the Spring and Autumn Period. Later, I almost forgot that he was mixed up with Tomb-Sweeping Day instead. Qingming was just the name of a solar term at first, and later became a festival to commemorate ancestors, which was related to the Cold Food Festival.

Ghost Festival is the Mid-Yuan Festival, also known as July 30 and Three Ghosts Festival, and Buddhism is called the Arahara Festival. The Mid-Autumn Festival falls on July 15th of the lunar calendar, partly on July 14th. It used to be Xiaoqiu, and a batch of crops were ripe. As a rule, people should worship their ancestors, provide new rice and other sacrifices, and report the situation in Qiu Cheng to their ancestors. So every Mid-Autumn Festival, every family worships their ancestors.

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. 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.
