As I made my way south through China, I got an idea: why not stop in Macau for a day? As it turned, out, it was quite easy. I took trains through Guilin and Guangzhou, and eventually ended up in the lovely city of Zhuhai. (One bonus of Zhuhai: it was the only place I had been in China where cars actually stopped for pedestrians.) From there, I just had to go through some immigration formalities and walk across the border, into Macau.
