I just came back and was told the check was safe

because it is only magnetic. Please go to www.tsa.gov to find the detailed instruction about what you can and can't bring with you, especially in the carry-on luggage. I had to buy a zip-lock bag at the airport because you can't bring lotion, shamppo, toothpaste and other stuff unless they are in the bag. Also the airline company has new weight restriction.

I got extremely sick on the airplane, please be prepared. If your seat is not close to the aisle, you may ask for an exchange so that you can more around easily.

Beijing was both warm and cold while I was there in Feb and March. But I had my sister's clothes to borrow. Mostly likely you can buy all the medicine you need in china, but what is made in USA is more expensive there.

Enjoy the food!
