I was looking for a picture of graffiti, little text input language, and I found the website dedicated to teachers who want to make these, you know, the script writing things across the top of their blackboard, and they had added graffiti to it, and I'm sorry about that.
我在网上找有关涂鸦的图片， 而发现这专为教师们而设的网站 他们教学中在黑板上写的， 而他们却把这涂鸦上了，真可惜，
