When is the laojunmiao Temple Fair in Tianshui?

Every year on the fifteenth day of the second lunar month. According to the public website of Tianshui laojunmiao, Tianshui laojunmiao was once built next to the mine. I don't know from which generation. After Daoguang Qing, there was a temple fair on February 15th of the lunar calendar, which was presided over by Taoist priests. Tianshui is a prefecture-level city under the jurisdiction of Gansu Province, located in the southeast of Gansu Province, which governs five counties of Qin Zhou, McKee, Wushan, Gangu, Qin 'an, Qingshui and Zhangjiachuan Hui Autonomous County and national economic and technological development zones.
