Lee & Sachi,
It is great to read about your travels. My wife and I spent the month of July traveling China. We spent three weeks teaching English to Chinese English teachers and one week of just traveling China. Your blog inspired me to create one of my own to document our travels through China.
We spent two weeks teaching in Wenling (5 hours south of Shanghai on the coast) and one week in Linhai. Ingrid and I had an amazing time and met many wonderful people who even invited us into their home for an authentic "home cooked" Chinese dinner. It took us quite a while to get use to the food, especially since we use to be vegetarians (good luck being a vegetarian in China). We also got to experience typhoon Bilis and narrowly missing two other typhoons. When you get to Shanghai I would suggest that you make a special effort to ride the MagLev (super train), which travels at 430 km/hour. I could ramble on for hours about our travels and experiences but I wont because you can read our blog if you are interested or have time to kill. I hope your experiences are as wonderful as ours were in China.
