Introduction to Zhongyi Pavilion: It is said that Song Jiang once set up a sword pavilion in the garden, where he often reflected on himself for fear of being unfaithful, filial, benevolent and unjust. Later, the 36 Tiangangs were transformed into 36 sharp swords hanging high on the pavilion. If someone who is unfaithful, unfilial, benevolent or unjust enters the pavilion, the sword will fall and the person will die in an instant. Later generations will call it the Loyalty Pavilion to distinguish between loyal and treacherous people.
