Where can I buy car models in Lanzhou?

On Binhe Road, about 500 meters east of Zhongshan Bridge, there is a shop called mannequin. The car models inside are all exquisite, but the price is relatively high. There is also a stall selling car models downstairs in the strategic pioneer Internet cafe of Gaolan Road Night Market. Although it is a stall in the night market, the car models there are also very exquisite and cheap, which is similar to the price on Taobao.
