It looks like I'm getting a double entry visa and so far I've done very little research into China.
I had only considered Shenzhen since I stay near to the Sheung Shui MTR station.
Now I am considering a longer stay in China to take better advantage of the visa.
What's near to Shenzhen and the next logical place to visit for a tourist?
I'm thinking of places I can get to without taking additional flights. Short train journey maybe....
