All Vegetarians visiting China!
Vegetarian dumplings can contain shrimp or some kind of seafood many times.
When you say bu yao rou, there still might be some seafood as it is not considered meat! Add "wo bu chi hai xian" along with "wo bu chi rou" when you order vegetarian food. Hope this helps!

Be careful if a street vendor tries to sell you a high end Laptop for very low unbelievable price! It will be rigged and the system information will be manipulated to show it as a high end system. Applies to cameras, watches etc

Some taxis ask whatever price they want. Laowais beware! I was told it would cost less than 20 rmb for wulinmen from train station. A taxi asked me 40 rmb. I took a bus and paid 1 rmb.
