I went there on the 4th of National Day this year. There are not many people. It is estimated that there are usually no people to go there. But the two families we went to liked it very much. People who are used to the southern landscape can feel the majesty and desolation of the northwest mountains and rivers. The scenery is very unique. To be honest, the rock painting seems to have no feeling. The style of the child graffiti, for those of us who have no research, can not see any doorway, but the scenery around Helan Mountain really refreshed us and unforgettable.
