Unique scenery: The most recommended section of the Chongzuo trip, a very typical karst scenery, under the blessing of cloudy days, it feels like a splash-ink landscape painting. Simple folk customs: There is no commercialization, the villagers are very nice, the prices are reasonable, you can eat in the village, and there are homestays to stay at cheap prices; the Heishui River is like a secret place that has not been conquered by tourists, there is no over-developed commercial sense, only the most authentic appearance of mountains, rivers and villages.
