Big gossip plays a big role, and small gossip plays a small role. Small gossip-shaped buildings or sculptures generally have certain functions of suppression, resistance, collection and dredging. Shanghai University, like Shanghai University, has a gossip-shaped fountain and flower pond in the center of the school. The center is low, and the inner and outer flower beds are staggered. The day after tomorrow, innate gossip is outside, and the inner gossip is dredged, and the outer gossip is taken. Generally speaking, it is a function of collecting and purifying. Bagua lives in the central fort of the school, which will purify and clear the air passage through. Moreover, this recessed flower bed and the prominent cylindrical building next to it are exactly one yin and one yang, which also balances the central gas field.
