Introduction to Qiankun Pavilion: The underground of Qiankun Pavilion is a Yin-Yang Tai Chi diagram paved with large stones, which corresponds to the Qiankun Bay at the foot of the mountain. Two lines of large characters are engraved on the pavilion pillars: "Heaven and earth created the Qiankun Bay, and Emperor Xi performed the Tai Chi diagram." Legend has it that ancestor Fuxi observed the heavenly phenomena in Qiankun Bay and invented the Tai Chi Bagua Yin and Yang theory. Later generations came here to visit their ancestors and pray for blessings.
