There are shops selling railway locomotive models in Heping Square, and there are remote control models on the second floor of Olympic Square, with cars, boats and planes. Huanghe road Hengda Model mainly sells remote-controlled airplane models and cars. There is a small shop called "Miss" in the middle of Shengli Shopping Corridor, which sells car models, novelty toys and animation toys. Assembled models are sold on the fourth floor of a large food market and in old buildings near Zhen Fu Building. I don't remember the exact location. There used to be shops selling model cars in Star Roosevelt and Fujia Xintiandi. Many shops have changed recently. I don't know if there are any more.
