Introduction to the Zhentan Stone: Longtan is surrounded by cliffs, and a stone rises in the middle, which is called the "Zhentan Stone". The stone body is rough and has many small holes. It can seat more than ten people on it and is connected by a natural stone bridge. "Fairy Bridge". Legend has it that there is a vicious black dragon locked in the Longtan. He wants to break open the stone that holds the pool day and night. The rumble of thunder is the roar of the black dragon. Later, a "kind" peacock came here and pecked out many small holes at the entrance of the town, allowing the black dragon to breathe. Guanyin found out and sent a roc to peck out the black dragon's eyes. Naturally, the black dragon could not break free from the cage. As a result, the Quzhou area had good weather and abundant food and clothing.
