《徐霞客游记·滇游日记三十》
望见西北方有层层山峰成排簇拥在岭上，起初以为将从它的南垂走，一里后，忽然从岭头转向北，三里，就向西南下到峡中，一里，有四五家人位于峡中居住，竹篱笆茅草房，觉得相当清静幽雅，这是赤土铺。
望西北有层峰排簇岭上，初以为将由其南垂行，一里，忽从岭头转北，三里，乃西南下峡中。一里，有四五家当峡而居，竹篱茅舍，颇觉清幽，是为赤土铺。
We saw layers of peaks clustering on the ridge in the northwest. At first, we thought we would walk along its south side, but after a li, we suddenly turned northward from the ridge head and walked for another three li before descending southwestward into the gorge. One li in, we saw four or five families living in the gorge, with bamboo fences and thatched cottages. It felt quite peaceful and elegant. This was Chitu Slope.
