Tomb-Sweeping Day is also called an outing festival, and the solar calendar is between April 4th and 6th every year. It is the season of bright spring and lush vegetation, and it is also a good time for people to go for a spring outing (called outing in ancient times), so the ancients had the custom of going for an outing in Qingming and carrying out a series of sports activities.

The traditional Tomb-Sweeping Day in China began in the Zhou Dynasty and has a history of more than 2,500 years. Qingming is first and foremost a very important solar term. As soon as Qingming arrives, the temperature rises, which is a good time for spring ploughing and sowing. Therefore, there are agricultural proverbs such as "planting melons and beans before and after Qingming" and "planting trees is not as good as Qingming".

Later, due to the approach of Qingming and cold food, and cold food is the day when people ban fire to sweep graves, cold food and Qingming gradually become one, and cold food has become another name for Qingming, and it has also become a custom of Qingming, that is, no fireworks are moved on the day of Qingming, only cold food is eaten. At the same time, the custom of worshipping ancestors and mourning the dead relatives in Tomb-Sweeping Day is still very popular today.
