Most people have heard of Hong Kong, but what about Macau?
Macau is another even smaller island that China considers its own, yet gives some form of independence.
Oddly enough, when travelling between China, Hong Kong, and Macau, everyone must have their passports stamped.
They even have their own political systems, their own police, and Hong Kong even had their own Olympic team during the 2008 Beijing games.
That prompted popular educator CGP Grey to ask the question, are Hong Kong and Macau their own countries?
