Hi Keann
For Shanghai, u can visit Xin Tian Di (pubbing and coffee time area). There's this restaurant serving Shanghainese food, nice but cant rmbr the name offhand.
Qi Pu Lu is another dest tat u shldnt miss! Wholesale centre for clothing, shoes, bags n accessories. Nanjing Lu is the sg Orchard Rd alike. Major shopping centres are found there. Ren Ming Guan Chang, Jing An Shi, Huai Hai Lu are oso shopping areas.
If u are into faked branded gds, can take the metro line to Shanghai Keji Guan station. Shld be within walking distance according to wat my Shanghai frenz told me when I was there.
Hope the info is useful to u.
