For sightseeing in Chengdu, you must go to Jinli Street, and you can shopping at Chunxi Lu, the most famous pedestrian street in Chengdu! Since most of the attractions of Chengdu are out of the city, such as Jiuzhaogou, Wolong National Natural Reserve and Sanxingdui Museum, anyway, you can look up at Chengdu Tours(https://www.travelchinaguide.com/package/chengdu.htm) for itineraries and attractions suggested.
