 The silt flooded into the Grand Canal in Shandong required major effort to repair.After the earthworks had been repaired, the Jingtai Emperor ordered the construction of two temples one at Heiyangshan and the other at Shawan and committed himself to praying personally to the river gods for flood prevention.By the sixth lunar month, the northern bank burst at Shawan again and the entire Grand Canal fleet was stranded by the sand thrown into its course.
