I want to buy a big photo to hang on the wall. Where can I develop such a big photo or make such a flat one?

You can go to the printing factory to print photographic paper, which is cheap. But the effect is still not as good as the photo studio. Your photo studio can develop. I am a photographer. There is a Hon Hai photographer on the south side of Jiefang Road Old Railway Vocational College (overpass), which specializes in developing photos. . It's cheap there. . When you go, just say so-and-so photography is ok
