Artemisia annua, autumn is strong. I went to see red-crowned cranes in early November. Unfortunately, the cranes are still moving south, and wild red-crowned cranes can be seen in late November. But the scenery of Wetland Park is beautiful, quiet and peaceful. We ride bicycles and sing along the reed marshes (revolutionary songs, as soon as we enter reed marshes, we think of guerrillas). They also took pictures of their children. The atmosphere of the reed marsh was not found anywhere else.
