On the way to Detian, when our bus turned to the mountain road, the scenery suddenly changed and became very beautiful. The roadside scenery along the road will never be lost to Guilin landscape when the bus crossed the Heishui River. The water on the left and the mountain on the right are scattered in the distance and near by small hills with abundant vegetation, emerald green, reflected in the water, and the river is emerald. We have been driving along such a road. More than an hour.
