The customs of the Dragon Boat Festival in Nanzheng County of Hanzhong are as follows: Ghost boat: Nanzheng County of Hanzhong has shallow water and cannot race dragon boats. Therefore, on the fifth day of May, papyrus was tied to a dry boat and taken to climb mountains and swim the streets. Wear the Five-color Line: In ancient China, five colors were worshipped, which were auspicious colors. Therefore, in the early morning of the festival, the first important thing for adults after getting up is to tie five-color lines on their wrists, ankles and necks. Children are not allowed to talk when tying the thread. The five-color line should not be broken or discarded at will, and can only be thrown into the river during a heavy rain in summer or the first bath.

Dragon Boat Festival is held on the fifth day of the fifth lunar month every year. Various folk activities, such as offering sacrifices, entertainment and health care, all originate from the seasonal custom of expelling toxin and evil spirits, including offering sacrifices to Qu Yuan, commemorating Wu Zixu, inserting mugwort leaves, hanging calamus, drinking realgar wine, eating zongzi and racing dragon boats to eliminate the five poisons. In May 2006, the State Council listed it in the first batch of national intangible cultural heritage list; In September 2009, UNESCO formally considered and approved the inclusion of China Dragon Boat Festival in the world intangible cultural heritage, making it the first festival in China to be selected as the world intangible cultural heritage.

Celebrating the Dragon Boat Festival has been a traditional habit of China people for more than two thousand years. Due to the vast territory, numerous nationalities and numerous stories and legends, not only many different festival names are produced, but also different customs exist in different places.
