The Tomb-sweeping Day is one of the 24 seasonal division points in China, falling on April 4-6 each year. After the festival, the temperature will rise up and rainfall increases. It is the high time for spring plowing and sowing. But the Qingming Festival is not only a seasonal point to guide farm work, it is more a festival of commemoration.
The Qingming Festival sees a combination of sadness and happiness.
This is the most important day of sacrifice. Both the Han and minority ethnic groups at this time offer sacrifices to their ancestors and sweep the tombs of the deceased. Also, they will not cook on this day and only cold food is served.
The Hanshi (Cold Food) Festival was usually one day before the Qingming Festival. As our ancestors often extended the day to the Qingming, they were later combined.
