宋神宗
During his time in the local administration, Wang Anshi gained an understanding of the difficulties experienced by local officials and the common people. In 1058, he sent a letter ten thousand characters long ("Wanyanshu"/"Yanshishu"/"Shang Renzong Huangdi yanshi shu") to Emperor Renzong of Song, in which he suggested reforms to the administration in order to solve financial and organizational problems. In the letter he blamed the downfall of previous dynasties on the refusal of their emperors to deviate from traditional patterns of rule. His letter was ignored for ten years until Emperor Shenzong of Song succeeded the throne. The new emperor faced declining taxes and an increasingly heavy burden of taxation on commoners due to the development of large estates, whose owners managed to evade paying their share of taxes. This led him to seek advice from Wang. Wang was first appointed vice counsellor ("can zhizheng shi"), and a year later was made chancellor ('zaixiang").
