Introduction to the ever-lasting incense: Since the establishment of Shuiyue Palace, the incense has not faded for more than a hundred years, especially during the annual birthday of Guanyin, there are even more people. On the day when "Guanyin opens the treasury", many people come here to wait the night before the "opening of the treasury". Men, women, old and young stay up all night and it is very lively. This grand occasion continues to this day.
