#20# Never think of the scene in front of Gansu Dingxi, driving more than three hours by car, all the hardships disappeared instantly in the tender green of the wolf-wet wetland. Like the loneliness and loneliness here, the stacks of terraces, the clouds floating in the distance, some unknown wildflowers. I want to leave the memory of a period of time here, and wait for the day when you pass by, pick it up.
