This card came from Augustus in Hong Kong. He wrote a few friendly words on the back of his card. He didn't write a lot, but when English isn't ones first language it can be difficult.
Augustus wrote, "Hello. Nice to meet you, my name is Augustus from Hong Kong. There are about 7650 skyscrapers in my city. I hope you'll like it. Happy postcrossing ~A"
I have visited Hong Kong a couple of times and have walked by some of these buildings. The bright lights are quite beautiful at night. Last time I was there, there was also a light and music show in the harbour. It was amazing!
I don't know much about the stamp, but it says that it commemorates 100 years of Girl Guides in Hong Kong.
