I have a 10 hour layover in Shanghai,any suggestion for a city tour & how to get there from airport

If you have about 10 hours, you can go to visit the Pudong area and the People's Square area.
The local subway line 2 can take you to reach Lujiazui, which is the center district of Pudong. Then you can also use the line 2 to reach People's Square Station. Get out of the station and then you travel see the People's Square and walk along Nanjing Road. If then, time is possible, it is suggested to go to Yuyuan Garden to have a look from Nanjing Road by taxi.

Thank you, Ali. Do you know if there are lockers that we can store our carry on bags in Pudong airport while we do the city tour? Please advise.

Yes, you can easliy find the Lugagge-left Counters at the terminals.

Thank you for your help.
