Where can I buy a local tourist map in Shanghai and how much does it cost?

Bookstores, newsstands, tourist attractions, railway stations, long-distance bus stations, etc. Can be used in many places. It’s hard to say the exact price. Nowadays, there are too many map versions of a city, and they are updated quickly and the prices vary, generally ranging from 2 yuan/copy to 10 yuan/copy. You can check it out when you buy it. Generally, the retail price is printed on the map, and the actual selling price will only be lower than the printed retail price.

Where can I buy a tourist map of Zhangjiajie, Hunan?

You can find it when you arrive in Zhangjiajie. You don't and I don't have to buy it. Like national forest parks, you can go by yourself. Zhangjiajie is a good place. The scenery is very good. It's glad you came. I went traveling last summer vacation. It feels very good. Prices in Zhangjiajie are not high either. Warm tip: Have your camera batteries ready, haha, just in case it’s not enough by then. Needless to say, once you get there you’ll realize it’s worth going. I wish you a safe and smooth journey!

Where can I buy the Beijing traffic and tourism map, the one where you can get discounted tickets if you buy it?

I bought one, it is also sold in the scenic spot. I bought it at the train station. This map is really good and you can get benefits and discounts from it. Anyway, I think it's good. It's much better than that fake map.
