I'm going to go there next year for 6 months and I hope to meet new friends here too, who can show me around^^ I have to go to shanghai for pretty much the same reasons as you: my uni sends me there to study chinese and have a work placement there. My worries are exactly the same as yours, really.. I'm afraid to go there alone (well there will be 4 ppl coming with me, but they keep excluding me from their activities, so I'm not that friendly with them
), so I hope to find ppl here I can visit during my stayand look forward to meeting beforehand.
Maybe I'll join some cosplay events there, should be great.
