《元史·列传·卷七十》
至正十六年，又上书皇太子说： 臣之所言即前日所进经典大意，殿下宜以所进诸书，参照《贞观政要》、《大学衍义》等篇，果能一一施行，则国家政务不难办好，太平之治不难达到。 
十六年，复上书皇太子，其言曰： 臣之所言，即前日所进经典之大意也，殿下宜以所进诸书，参以《贞观政要》、《大学衍义》等篇，果能一一推而行之，则万几之政、太平之治，不难致矣。

If you can implement them one by one, it will not be difficult to manage the state affairs and achieve peace and prosperity.
