Hehua Hall, also named the 6th hall, was built by Wu Peigao [1741-1804, Yixiangsheng (Xiucai)], the 31st generation of the Wu family. The elderly member Wu Xianggui said the original site of Hehua Hall was a lotus pond. It is also said that the original owner of the lotus pond was a devout Buddhist, and after the house was built, no livestock or poultry were slaughtered in it. Buddhism regards the lotus flower as a holy flower, using the lotus as a metaphor for the Buddha, symbolizing the birth of a Bodhisattva in the midst of the troubles of life and death, without being disturbed by them. In Buddhism, it is said that “when the flower blossoms, the Buddha's nature is revealed”. The holy nature of the lotus flower, which emerges from the mud without staining, represents the Buddha's and the Bodhisattva's transcendence of the world and all that is empty. The root of lotus does not die, but grows again the next year, symbolizing the eternal cycle of birth and rebirth.

The lotus flower in Buddhism, has sacred significance. The Buddhist scriptures refer to the sacred flower as the 'lotus', and to the kingdom of Buddha as the 'lotus world'. His robe is the 'lotus garment' and the monk's handprints when performing Dharma are “Lian Hua He Zang (folded palms that look like the bud of a lotus flower)”. The Buddha, Sakyamuni, is even referred to as the “Lotus Prince”. The lotus is the only one plant which flowers, fruits (roots) and seeds (lotus seeds). The lotus is a symbol of the Triple body of Buddha – body of essence, body of communal bliss, and body of transformation.
