Introduction to the ancient stage: The ancient stage is located on the east side of Dalongtan, facing south and facing north. It was first built in the Ming Dynasty and rebuilt in the Qing Dynasty. It is a building with the style of ancient temple fairs. Legend has it that the 19th day of the second lunar month is the birthday of the Dragon King, so people will offer sacrifices to the Dragon King from the 19th to the 21st. People from all over Yuxi will come to Jiulong Pond from all directions to perform operas here for three days, with huge crowds of people and an unprecedented grand occasion.
