Although I spend most of my time in Zhuhai, I travel frequently around the Pearl River Delta. If you want to build an illegal business, this is the best place to start. Best place for prostitution, best for money laundering, best for operating gambling den, you name it you have it. It is also a hideout for wanted criminals. Nevertheless Guangdong is a beautiful place to visit.
To all that love Chinese cuisine, Guangdong must be one of the places you have to visit.
