Introduction to the open-air teahouse: There are some tables and chairs scattered in the open space in front of the teahouse for tea guests to drink tea in the open air. But the location of this table and chairs is a bit special. Directly under the table is a well. The ancient well Xuanmiao Spring was left by the sword of the Ming Dynasty. The well is 6.5 meters deep. The walls of the well are made of thick and heavy bricks and are in a hexagonal shape. The water is clear and sweet. It lasts all year round. It was discovered during the renovation of the guild hall and effectively protected. "Quan" means "money".
