《徐霞客游记·滇游日记十四》
过了桥，往南上坡，一里，登上坡，靠着西山往南走、三里，山坞从南边伸来，在山坞东北边山上有座塔，于是沿着西山往南下，半里，抵达坞底，又走半里，看见有条河贯穿坞中，石桥横跨河上，这桥名土桥。
《志》曰承恩。过桥，南上坡，一里，登坡，倚西山南行。三里，其坞自南来，有塔在坞东北山上，乃沿西山南下，半里，抵坞底。又半里，见有水贯坞中，石梁跨其上，是名土桥。
Go across the bridge, and go up the slope to the south. One mile, go up the slope, and lean against the west mountain and go to the south. Three miles, the mountain dock came from the south. There is a tower on the mountain to the northeast of the mountain dock, so follow the west mountain and go south. Half a mile, reach the bottom of the dock, and walk another half a mile, and you will see a river running through the dock. A stone bridge crosses the river. This bridge is called the Tu Bridge.
