This time I went to Beidaihe for training and went for a walk on the boardwalk at night. I have to say that this is the most pleasant plank road I have ever walked. It is said that I can walk to the downtown area of Qinhuangdao along the plank road. Along the plank road through the wetland, it may be the wrong time to go, but I didn't see any birds, but the view is very wide, you can see the pigeon nest far away, and the sea is when you walk to the shallow water bay.
