The fifth floor, the basement of Jin Hui shopping mall, and the Great Hutong. I know what you mean by graffiti! There must be Mai Mai, because I have taken photos. I remember that when I took pictures before, it seemed to be more than 40 yuan! ~ I made a big version, and now I don't know how much it costs. You have to go there to choose the specific style and version, and the price is different for different versions! ~
