 In 1188, Zhangzong's grandfather and predecessor Shizong (r. 1161–1189) had ordered the woodblocks for the Song Canon transferred from Kaifeng (the former Northern Song capital that had now become the Jin "Southern Capital") to the Central Capital's "Abbey of Celestial Perpetuity" or Tianchang guan 天長觀, on the site of what is now the White Cloud Temple in Beijing.Other Daoist writings were also moved there from another abbey in the Central Capital.Zhangzong instructed the abbey's superintendent Sun Mingdao 孫明道 and two civil officials to prepare a complete Canon for printing.
