Legend has it that after Ge Hong became immortal, he left a pool for the world, which is connected to the Heavenly Court, and as long as you turn your back to the pool and toss a coin into the water from above the shoulder and make a wish, you will have the opportunity to let the gods hear you and fulfil your wish. At the same time, the Wishing Pool is also a symbol of love, and legend has it that when couples put coins into the pool together, love will last forever. As a place for people to place their hopes and pray for good luck, the wishing fountain is also a part of cultural practice.
