Vietnam is one of the few countries in the world that use the same lunar calendar as China. The Ching Ming Festival is a day for Vietnamese folk to visit the graves of their ancestors and trekking. Cold Food Festival is celebrated on the third day of the third month of the lunar calendar. Cold food means eating cold food. This festival also originated in China and was later introduced to Vietnam. According to Chinese customs, Vietnamese people also celebrate the Cold Food Festival, partly to remember the loyalty of Jie Zi Tui and partly as an opportunity to honor their ancestors. However, the Vietnamese do not prohibit smoking, do not eat cold food, and do not need to make all kinds of food on the first day. Two other types of food for the Cold Food Festival are Lantern Festival and Soup Dumplings. Vietnamese people say that March is the season of Lantern and Soup Dumplings because it is only from March that Vietnamese people start to eat Lantern and Soup Dumplings. The Vietnamese dumplings are also made of glutinous rice flour, but the flavor and the way of eating them are different from those of Chinese dumplings. Vietnamese dumplings are filled with icing sugar and are smaller than Chinese dumplings. They are put into boiling water, sink and float for a few times, and after being cooked, they are fished out and put on a small plate. Vietnamese dumplings are filled with green beans. The mung beans are boiled, peeled, mashed, and then wrapped as a filling in the dumplings. The dumplings are also boiled in boiling water and then put in a bowl, not in a dish, and eaten with sugar water. In the past, Vietnamese people didn't eat Lanterns and dumplings before the third day of the third month of the lunar calendar. This is because it is only from the Cold Food Festival on the third day of the third month of the lunar calendar that they begin to sacrifice their ancestors with the Yuanxiao and Tangyuan. In the spirit of honoring the gods and ancestors, there are foods offered in each season for each season, and people cannot eat such foods by themselves first until they are offered. Nowadays, in Vietnamese cities, few people celebrate the Cold Food Festival. However, the custom of eating Lantern Festival and soup dumplings in March still continues. On the streets, people can also see a lot of women selling Lantern and soup dumplings.
Ching Ming Festival Qingming is the fifth of the 24 solar terms of the year and comes 45 days after the beginning of spring. Qingming usually falls in the third month of the lunar calendar, and at the latest in the beginning of the fourth month of the lunar calendar. Qingming, meaning clear and bright, is a beautiful time of the year. In the Orient, Ching Ming is regarded as an important festival of the year. Like in China, Vietnamese people also take the opportunity of Tomb-sweeping and trekking on the occasion of Tomb-sweeping. People bring shovels, flowers, incense, paper money, etc. to repair graves, remove weeds from graves, burn incense and paper, and in some cases offer flowers. In many places, there is also the custom of setting off firecrackers when sweeping graves. In the bright spring time, people's spring tourism activities are particularly lively. Some key tourist areas are crowded, endless.
