Da zhong dian ping （大众点评） is the Chinese Version of Yelp. I used it a lot in China. Actually, after I came to United States, I started the app out of habit. Then the app automatically switched my location to Washington. Just like how it worked in China, it started to recommend me some place to eat around the campus and also museums. It also showed me the way to the nearest Macy’s and issued some coupons. I am really surprised that this app is working worldwide whilea lots of Chinese app has a strong area restriction. I think what I would change is that instead of just giving recommendations, I would also have some functions like “paying the bill on line with a discount”, “place order and free pickup” since it has those functions in China and it worked out really well. To increase the usability world wide, or have it attached to some other software like paypal to make it easier for people to use it because payment is always what people care about the most. Also, Chinese has extremely awesome food delivery system. If they can enable users to enjoy a more convience delivery system, it woul dbe really great.
