《元史·列传·卷九十二》
桑哥认为，总制院所辖的西蕃诸宣慰司，管理军民财谷，事关重大，应该把这个机构的级别再提高点，以示其尊崇而与其他机构不同，因此，建议改为宣政院，官秩一品，用三台银印。
桑哥又以总制院所统西蕃诸宣慰司，军民财谷，事体甚重，宜有以崇异之，奏改为宣政院，秩从一品，用三台银印。
Sangge believed that the Western Commissioner's Office of the General Administration Office managed military affairs, and finances and was of critical importance. This organization's level should be more elevated to emphasize its distinction from other organizations. So, it is recommended to change its name to the Office of Xuanzheng, with the rank of the first grade, and to use the silver seal of the three divisions.
