We walked along the river and listened to the sound of the water. As we approached the next station, we saw a waterfall about 5 meters high in the middle of the river. When the mountains on both sides of the long flowing water valley, different rock formations could be seen. Some are covered with yellow sand very deep, some are relatively shallow. Others are directly exposed outside. From time to time, I also see some rock paintings that people don’t know when they are portrayed. It is worth a visit.
