flora, I have been to China twice, and the only Chinese word I know is sheshe. I know a few others, only because one of my best friend was a Chinese, and I've known him for 44 years. He passed away two years ago. Yes, China is developing fast - to which I can attest, because I visited in 1992 and in 2000, and saw the big change 1) many tall buildings in Beijing, 2) more cars and less bicycles, 3) much cleaner, 4) new Beijing International Airport, and 5) more shops and restaurants catering to the middle class. We had tour guides some of the time, but we were able to walk all over Beijing by ourselves, take taxis to different places (by having our hotel write the destination and the name of our hotel in Chinese), and eating at restaurants by pointing.
Does Beijing still have the silk market? I have also visited Xian, Shanghai-2xs, Gauilin, Guangzhou, and Hong Kong-2xs.
