“The thirteenth day of the fifth lunar month is the birthday of Guan Gong. Local authorities offer sacrifices to him in the temple by the Zhou Tai Bao Bridge. People start buying cooked meat and put on stage performances before the 13th. Tens of thousands of bright lamps are lit. People worship with sincere prayers. It is also said that the thirteenth day of the ninth lunar month is the day when Guan Gong was apotheosized. The ceremonies on these two days are identical. It is popularly believed that if it rains on these days, it happens because Guan Gong is wetting the whetstone on which he sharpens his long-hilt sabre. The rain presages the well-being of the people.” – cultural-china.com
