Is Daqing Taiqing Palace all true or only one?

It's all true. Taiqing Palace is a famous Taoist ten-square jungle in Northeast China, and it is also the center of Taoist activities in Northeast China in history. According to A Brief History of the Jungle in Taiqing Palace, from the third year of Daoguang in Qing Dynasty (1823), an abbot, Sun Bao, lectured on scriptures and precepts in Taiqing Palace to the thirty-third year of the Republic of China (1944), more than 2,000 disciples were ordained.
