I had no idea that Macau an administrative region in China, let alone exist.
The postcard shows the European style buildings. When I saw the stamps were written in Portuguese, I googled it and found out that Macau was a Portuguese Colony in China! Not only that, it was handed over to China in 1999. So their main language is Chinese and Portuguese.
The Sopa de fitas com van-tan on the stamp made me hungry.
