China is an amazing place.  I lived in Shenzhen for three months, and had such a wonderful time.  In a town with about 7 million people, there was always something to see and explore.  I still only speak a little Mandarin, but I am not so sure it is understandable.  I hope to go back again and see more of China someday.  I made several trips to Hong Kong, and it was an amazing adventure.
