One wrong word means that there are two wrong words in the front door. Reading bird books refers to a statue made of stone that looks like a bird from the outside and looks like a book from the inside; "Inclined door" and "inclined road" mean that the door is inclined and the road is inclined.
The most interesting thing about Xiamen University is that the road at the main entrance of Xiamen University is not perpendicular to the old Jiageng building built in Chen Jiageng.
The school gate is built along the road, and it must be inclined. The road and the school gate are also inclined. At the same time, there is a sculpture at the school gate. The front looks like an open book and the front looks like a flying bird.
Therefore, there is a saying in Xiamen University: "Love to go to Xiamen University and read bird books sideways".
