Bosideng's headquater is in Hangzhou, but its factories seems not in Hangzhou. Hangzhou has a Silk Museum in the south bank of the West Lake.

the Headquarter of Bosideng is in Changshu Bosideng Industrial Zone,Suzhou.

and here's the silk institute: Suzhou Silk Science Research Institute Economic Development Co., Ltd.

from Shanghai railway station to Suzhou just 15 minutes by train.

my home is in Suzhou near Taihu lake.be free to ask any question about Suzhou.Welcome!

Thank you for this information, it has all helped greatly :) i'm looking forward to the trip (even though it is only for one week including travel) i am hoping to gain a huge experience out of this as i love the chinese culture and wish to learn more through experiencing it. my boyfriend wants to take me there and spend between 3 - 6 months out there after he has done army training and i have finished my college course. we will be bringing his little 3 year old boy and it will be nice to know at least a few places for us to visit. one of the people i work with is from Beijing and has offered to teach me some of the Mandarin and Cantonese language so i can ask people things when we get out there. she has even offered me a place to stay when i visit with my boyfriend and his son. i absolutely can not wait till March. thank you :)
