《徐霞客游记·滇游日记四》
这时，笼罩群山的云雾也散开了，于是看见西坞在群山之中高悬，东部所下的山，和西部高大的山峰对峙于山路两旁，南部北部的群山之中劈开很深的沟壑，而拐泽河从北往南从沟壑中流过；这里地貌形势虽然见到了，但拐泽河水还深嵌在沟底而无法看见。
其时雾影亦开，遂见西坞中悬，东界所下之山，与西界崇峰并夹，南北中辟深壑，而拐泽河自北而南，经其中焉；其形势虽见，而河流犹深嵌不可窥。
At this moment, the clouds and mists veiling the mountain ranges had dissipated too, and so Xiwo was seen high in mid-air within the mountain ranges, with the mountains heading east taking a position opposing the tall mountains of the west towards both sides of the mountain pass, while the mountain ranges in the south and north had gorges and gullies deeply split in between them; and the Guai Ze River flowed through the gullies and gorges from north to south; although the geomorphology could now be seen, the waters of the Guai Ze River were still deeply set in the riverbed and could not be seen.
