Three days is perfectly reasonable for a quick trip to Shanghai. You can see skyscrapers and century-old architecture, and try pan-fried dumplings or have a drink in a fancy bar with a river view.

Route 1: Must see spots
Walking east on Nanjing Road will lead you through one of China's busiest shopping streets. You will arrive at the banks of the Huangpu River, known as The Bund. This is one of the jewels of the city.
Route 2: Good taste
If you are not satisfied by the glitzy, new, Western side of Shanghai, then perhaps visit the Yuyuan Garden. It is a private garden built in the 16th century that is now a renowned scenic spot, famous for old restaurants, a teahouse and Western snacks. A dumpling restaurant called Nanxiang has enjoyed popularity for more than a century.
Route 3: In the suburbs
A 50-minute drive will take you to Zhujiajiao, a suburban water town to the west of Shanghai. Traditional handicrafts, food and ways of life can still be found. Guides take tourists on a boat ride through the waterways lined with centuries old houses.
If you prefer to see some nature, Metro Line 9 will take you to the Chenshan Botanic Garden in Songjiang district where beautiful garden landscapes and around 9,000 distinctive plant species are on display.
