What festival is the health and epidemic prevention festival?

June 12 is the traditional festival Dragon Boat Festival. According to folklore experts, judging from some customs and eating habits of the Dragon Boat Festival, the Dragon Boat Festival is rich in medical and health care contents, which can be called the earliest "health and epidemic prevention festival" in China.

In ancient times, May was commonly called "evil month" and "poisonous month", and the fifth day was also called "evil day" and "poisonous day". The fifth day of May is evil month and evil day, which is the most taboo for people. Therefore, in the old society, health care and epidemic prevention were the main principles of the Dragon Boat Festival, and special customs such as inserting wormwood leaves, drinking realgar wine and tying colored silk thread were formed to ward off evil spirits and avoid epidemics.
