1, China people have the traditional virtue of "thinking about the source when drinking water". According to Lu, in ancient times, every time in Tomb-Sweeping Day, no matter the dignitaries or ordinary people, they would go to the grave to worship their ancestors and express their respect and nostalgia for their ancestors. On this day, sweeping graves is the most important activity. However, in some parts of our country, the custom of eating cold rice in Tomb-Sweeping Day still remains.

2. Green Zongzi was once a grave-sweeping sacrifice in Tomb-Sweeping Day, south of the Yangtze River. The skin is mixed with glutinous rice, and the stuffing is very rough. Legend has it that at the end of the Qing Dynasty, a woman named Zoe in Zhengyi Town found that a kind of soy sauce wheat straw was a good raw material for making green juice of green glutinous rice balls, while the glutinous rice balls made by hand grinding were softer and more delicate, not sticky, and did not break, harden or change color after being stored for several days.

Before and after Tomb-Sweeping Day, there were many traditional colorful cultural and sports activities, such as tug-of-war, swinging, flying kites, playing polo and fighting cocks. Tomb-Sweeping Day's customs are rich and colorful, and there are many records in past dynasties. The poet's works with clear thinking are even more wonderful and unforgettable. In these senses, Qingming is both a solar term and a traditional festival. This is an opportunity to mourn. Teenagers from all over the country flocked to the Martyrs Cemetery to pay their respects, or invited revolutionary ancestors to give reports and tell revolutionary stories, or organized tours, trips, visits to places of interest and collect specimens, which enriched the content of the festival.
