Introduction to Shanghai Password: Shanghai Password can be called a miniature miniature museum of retro glasses from the world. In the small and exquisite space, the pure white brick walls are covered with fashionable old posters of French eyewear brands, paired with old rusty chains, and filled with old-fashioned handmade glasses from France, Germany, and China. In addition to the flagship retro glasses, Shanghai-brand vintage watches and notebooks are also quite outstanding. Inadvertently, you can also see the Phoenix license plate hanging on the wall.
