Of course, the most important thing we can't miss in Xiamen University is the Furong Tunnel. It is said that the Furong Tunnel was once a huge civil air defense project, but now it is not a trace. Once the Furong Tunnel was clean and open, with rows of fluorescent lights, front and back security, and no motor vehicles were allowed to pass; even walking in the tunnel at midnight, it was quite safe. Sitting on a bicycle whistling, or singing, the sound echoes back and forth on the wall, very happy feeling. Between one day and one night (or afternoon, to be exact), the white walls of the tunnel were suddenly covered with more graffiti, and then more graffiti appeared in succession, with different styles and colours. Then, the graffiti in the tunnel develops from the headquarters and Zeng Chuan'an to the center respectively, and the theme is very different: the headquarters belong to Tianma Xingkong creative area, mostly campus publicity and graduation memorial, while Zeng Chuan'an district is heavy, with the theme of commemorating 5.12. [5] The murals here are very creative and exquisite. Perhaps the beautiful campus can cultivate students with artistic flavor? And some of them will resonate with me at once, so let's enjoy the pictures.~
