I am staying in Shanghai university, looking for clothes shops in the city.

Do you refer to the campus located at no. 99 of shangda road?
If so, you can go to Orient Shopping, located at No. 800 of east Nanjing road.

You can walk to SH university subway station to take the line 7 to changshu road station, where you can transfer to line 1 to People’s Square. Take the Exit 20 and walk about 380 yards to the destination.
