When i was in Beijing in 2006 (alone but that is another story) i took a few tours using Gray's, now i must say they give good service and a good lunch and like most tour companies they stop for the obligatory "shopping trip". The silk factory is interesting and the display of how they make doona's is quite informative, they then try and sell you silk pillows, sheets, and other manchester. What they don't tell you as you are left to wander past rows of sheets etc that the clothing and robes etc are up on the third floor, so as soon as they have finished the demonstration head off up there, more time to browse as there is a HUGE selection of shirts, dress, robes etc. Got some really good 100% silk robes for my neice and daughter and sister, and some nice shirts for myself and my some. The good thing about silk shirts is they don't need ironing! which is a bonus for a single man. (Then not now).
