In their eyes, keeping teeth as white as jade is a sign of bad quality and bad style, while dyeing teeth black and bright is the most beautiful. Festivals Vietnam also uses the solar calendar and the lunar calendar. In addition to national statutory holidays such as New Year's Day, International Labor Day, National Day, etc., Vietnam also celebrates Tomb Sweeping Day, Dragon Boat Festival, Ghost Festival, Mid-Autumn Festival, Double Ninth Festival, Spring Festival, etc. Like the Chinese, the Spring Festival on the lunar calendar is the biggest festival of the year. There is a folk song in Vietnam: "Fat meat, ginger and green onions with red couplets, flags, firecrackers and big rice dumplings." It means that when the Spring Festival is here, you should prepare sumptuous meat dishes, cook rice dumplings, and put up red couplets and high flags on the door. Flags fluttered in the wind and firecrackers sounded. From this folk song, we can see how much Vietnamese people attach great importance to the Spring Festival. At the transition between the new year and the old year, Vietnamese people also have the habit of keeping the year old. On New Year's Eve, people usually sing sleeping songs for the entertainment of local soldiers, which later spread among the people. The so-called military drum is actually a wooden or iron barrel. Two pillars are erected at the end of the village. The barrel is tightened with hemp rope or steel wire and fixed on the pillar. The rope is struck with a stick to make a ringing sound. The men and women stood on each side, singing to each other while knocking, laughing and singing together, and the atmosphere was cheerful and warm. Some young men and women establish feelings and establish love relationships through antiphonal songs. Ancestor Worship Vietnamese people, like other Orientals, pay attention to filial piety. In every family, it is indispensable for children to honor their grandparents and parents. The Vietnamese worship their dead ancestors very deeply, so they attach great importance to their ancestor worship beliefs and inherit them from generation to generation, forming a large scale. People believe that although a loved one dies, his soul still exists, plays a role in protecting and supervising future generations, and dominates all people's activities. Many disasters and blessings in the world depend on the blessing and relief of the ancestors. Every Vietnamese household has a shrine, a shrine, or a shrine. It is an altar to worship ancestors and a holy place to worship ancestors and gods. No one can offend it, and no one can have any dirt on it. In the city, due to the cramped living quarters, the altar design was small and varied. Such as nailing a board to the wall or using the top of a cabinet as an altar to worship ancestors. An incense burner is placed in the center of the altar, with two incense candles on both sides. A thin red lacquered wooden plate or plastic is placed in front of the incense burner. There are fruits in glass dishes, a pair of vases and a number of cups and saucers for sacrificial offerings. There are also couplets posted on both sides of the altar in some families, such as "The merits of the ancestors flourish for thousands of years, the sons and daughters are filial and the virtuous and virtuous are prosperous for thousands of generations", "The family is prosperous with blessings and rituals, and the wealth and wealth are prosperous", etc. The Vietnamese regard worshiping their ancestors as an important matter, and use it to express gratitude to their ancestors for their upbringing. Although many families have different religious beliefs, worshiping their ancestors cannot be ignored. Before the Spring Festival comes, the altar must be rearranged, incense candles must be inserted, and offerings must be placed. During the three days of the Spring Festival, the altar is always lit with incense, and parents and clan members pray before the family has a reunion dinner. Vietnamese people's worship of ancestors is also reflected in taboo names. In normal times, descendants should avoid mentioning the names of their ancestors and fathers. If some nouns overlap with the names of their ancestors and fathers in real life, they should avoid them or use synonyms instead. When children are young, parents do not let them know the names of their ancestors to prevent them from shouting randomly and disrespecting their ancestors. If someone points at the name of an ancestor and ridicules or insults him, the person being ridiculed or insulted will think that he has suffered a great shame and humiliation, which will arouse deep hatred. In recent years, taboo names have become less common in cities, but in rural areas this custom is still maintained. In addition to worshiping ancestors, ancient Vietnamese people generally had superstitious beliefs about city gods, divination, astrology, Feng Shui, spirits, etc. All natural objects and natural phenomena, such as rivers, lakes, mountains, big trees, wild beasts, wind and rain, etc., in their minds, have spirits residing in them, and they should be worshiped and sacrificed in order to ward off disasters and bring blessings. For example, in Kim Lien Village in Don Do District, Hanoi, there is still an inscription of the God of the Mountain King, erected in 1510. In rural areas, the earth god, banyan tree god, snake god, tiger god and the center stone of the village are usually worshiped. Center board etc. People sacrifice it in places where tigers often hang out, and they must not offend it in their words and deeds, calling it "the king of the mountain" in a low voice. If you encounter a tiger, not only cannot you kill it, but you must also offer various sacrifices.
