《明史·列传·卷二百零三》
原先，曩罕弄私自占据孟密时，将孟密从木邦中分离出来。但她也担心邻近边境地区不平静，便派人从小路抵达云南，又从云南到达京城，向朝廷贡献宝石和黄金，请求朝廷在孟密开设治所，让孟密直接隶属于布政司的管辖。
五年，南甸州奏： 先被麓川宣慰司夺其境土，赖朝廷威力复之，若不置官司以正疆界，恐侵夺未厌，乞置四巡检司镇之。 
Originally, when Nang Han Nong privately occupied Meng Mi, he separated Meng Mi from Mu Bang. However, she was also worried that the border areas would not be peaceful, so she sent people to Yunnan by a small road, and then from Yunnan to the capital, to pay tribute of precious stones and gold to the court, and to request the court to establish an administrative office in Meng Mi, so that Meng Mi could be directly under the jurisdiction of the provincial administration.
