Gambling
China has very interesting gambling laws. The lottery, online slot machines, and sports betting are fine and legal... but, poker? No, way. Poker, mah-jong, and other casino activities are illegal.
The Police Geese
Don't even try to run from the police geese. There are several police stations in China's Xinjiang Uygur autonomous region that has employed squads of geese to ward off threats and guard their bureau. Apparently, they are more effective than guard dogs thanks to their keen eyesight and pure malice. Don't even try to outrun them.
