The origin of Qingming Festival (Tomb-Sweeping Day) is as follows in English:

The Qingming Festival, also known as Tomb-Sweeping Day, is a traditional Chinese holiday that holds great significance in the Chinese cultural heritage. Its origins can be traced back to the Zhou Dynasty (1046-256 BC).
The festival is believed to honor the spirits of one's ancestors and express gratitude for their support and guidance. The exact origin of Qingming Festival is not clear, but there are several legends explaining its roots.
One story tells of Yu the Great, who subdued the floodwaters and saved the people from disaster. According to this legend, Emperor Yu was so busy with his work that he couldn't offer proper respect to his ancestors. His people felt sorry for him and helped him perform the rites. Since then, the Qingming Festival has been observed to show respect for ancestors.
Another legend is connected to Qu Yuan, a famous poet of the Warring States period (475-221 BC). Qu Yuan drowned himself in the Miluo River after being unjustly exiled from the court. To prevent fish from consuming his body, his followers threw rice into the river. Later, it became a tradition to throw food and paper offerings at graves during the Qingming Festival.
The Qingming Festival is typically celebrated on April 4 or 5 of the Gregorian calendar, according to the Chinese lunar calendar. During this time, families clean and pay respect to the graves of their ancestors, burn incense, offer paper money, and present food and drinks as a sign of respect and remembrance. The day also features other activities like flying kites and enjoying spring outings.
