Thank you Echo! I know, the middle class is probably not one spcific group in China so it's hard to say what the average middle class income is, but that's what I was asked to find out! Thank you anyway! By the way, I was in Beijing recently and finally had the the chance to eat some 地道北京烧鸭! Wow, it was so good! I've eaten in before in 贵州, and I really liked it, but it's nothing like the real thing!
