Here are some things I wish I had right now! If you are traveling soon you might want to consider the following items:
1. napkins--if you get a napkin with your meal it will be a small dessert napkin. Most places don't supply one at all. Also, if you don't want to use chopsticks, bring plastic ware to the restaurants. Most don't have forks, spoons, etc.
2. small, scented garbage bags or--bring garbage bags to dispose of dirty diapers (or plastic shopping bags).
3. a travel clock. Our hotel room does not have a clock. We are staying at the White Rose in Wuhan, Hubei Province. I never know what time it is unless I look at the computer or my watch but I like to see a digital display!
4. laundry bag--you will need to do laundry while in China and we have had need for a laundry bag. Be sure to write your name on it so that you get your items back! We currently have a rogue pair of underwear!
I will keep adding to the list as I find things that seem necessary.
