i live in yuen long in Hong Kong , how am i suppose to go to the Window of the World?

You can take the MTR West Rail line at the Yuen Long Station and get off at Hung Hom Station. Then transfer to East Rail Line and get off at Lo Wu Station. After passing the border to SZ, you can take the subway Luobao Line and get off at the Window of the World. Then walk to your destination.
