Furong Tunnel is a famous attraction of Xiamen University. Yesterday was Sunday. When I arrived at Furong Tunnel, there were a lot of tourists, especially students. There were primary school students and junior high school students at the age. There were many parents with their children to visit here. The hole is very long. It should be about one kilometer. The tourists who participated in the group left near the hole, and I walked through the entire tunnel to explore the end, and then returned. On both sides of the cave wall, there are graffiti works left by graduates of Xiamen University. Some works are quite interesting. Walking in the tunnel to feel the romantic life of young people, as if they were back to the university student era!
