《徐霞客游记·滇游日记三十三》
它的山脉起自于昆仑山，南下至姊妹山；往西南延伸的，成为滇滩关南面的高山；向东南延伸的，绕过小田、大塘，往东到马面关，就弯然向南耸起，横架在半天之上，成为雪山、成为山心、成为分水关；又向南抵达芒市，才降低稍稍散开，它由南到北高大弯隆的山峰，儿乎有五百里；由芒市到达木邦，下延成为平缓的坡地，直达缅甸而后在海边到了尽头：确实是昆仑山正南的支脉。
其发脉自昆仑，南下至姊妹山；西南行者，滇滩关南高山；东南行者，绕小田、大塘，东至马面关，乃穹然南耸，横架天半，为雪山、为山心、为分水关；又南而抵芒市，始降而稍散，其南北之高穹者，几五百里云；由芒市达木邦，下为平坡，直达缅甸而尽于海：则信为昆仑正南之支也。
Its mountain range starts from the Kun Lun mountain, heading south to Zimei mountain; extending to the southwest, it becomes the high mountain to the south of Dian Tan Guan, extending to the southeast, goes around Xiao Tian, Da Tang, heading east to Ma Mian Guan. It then rises up sharply towards the south, extending across the sky, becoming a snowy mountain, a mountain heart, and a water divide. Heading south, arriving at Mang Shi, it tapers off, becoming slightly spread out. From south to north, the lofty, bending and swelling mountain peaks are approximately 500 miles. From Mang Shi, arriving at Mu Bang, in the descent, there are gently sloping hillsides, extending to Myanmar and finally to the ocean. It is truly a main branch of the Kun Lun mountain range to the south.
