Where can I find a shop that makes star posters and star badges and hats in Shenyang?

If it's a poster, you can go to a general copy agency to make it for you, or print it quickly. It used to cost 6 yuan to make a poster, that was five years ago. For hats and badges, there are related shops in Northeast Subway, Ai Wu Street, Shenyang Spring and Taiyuan Street Fashion Subway, but you must take the time to find them.
