Naadam, also known as "Nair", means "entertainment" and "play", is a grand traditional festival for the Mongolian people. Naadam is ancient and sacred for Mongolian people. It has a long history. The earliest record of "Naadam" activity is Genghis Khan inscribed on a stone cliff in Mongolian in 1225 AD.
Xingmeng village, where the Mongolian people live in Tonghai County, has held "Naadam" activities since 1979. It lasts for three days from December 11 to 13 every year. The content of Naadam meeting in Xingmeng village has been changed into dragon dance, golden phoenix, bonfire party, colorful boat, rowing dry boat and other cultural performances according to local customs. In recent years, archery, horseback riding, and wrestling competitions of "Naadam" in the grassland have been restored. The "Golden Phoenix" with a family letter in its month tells the Mongolian missing their northern hometown from the south territory. Rowing dry boats, playing dragon lanterns and shrimp lanterns, jumping clamshells, etc. reflect the hardships of the Mongolian people who settled in Yunnan in the Yuan Dynasty changed from herdsmen to fishermen. All performances have strong ethnic characteristics. During the festival, according to traditional customs, all villages slaughter pigs and sheep for collective dinners.
