Hi, your question would sound better if you wrote: How much do you know about China? I have been to China on a study tour and loved meeting all the friendly people and visiting all your famous tourist attractions.

I know China inside out and I also have the Chinese history (中華五仟年), A collection of more than 900 series, Additiohally, my grandfather of my mother side, he told me the story while he was a professor at Peking University, his experience with Mao Tse Tong

I know China too!

Of course, who doesn't know of China?
