I ran to Rhine Falls, the largest waterfall in Europe. I thought it should be over 6 p.m. local time, but it was still super sunning. When I got off the train, I saw that it took 15 minutes to walk the signpost, and I felt like I had to kneel down on my chosen road and finish it. But the waterfall is clear to the bottom and the rainbow is not in vain. In the stained glass room, I met Dangdang, a Shanghai kid, who had to play with me all the way. Later, I thought they had gone. I found Dangdang was still waiting for me in the hot sun with sweat on his head.
