The one thing that struck me about Hong Kong was the billboards. They are huge and even bigger when they are that close to the ground level. Some might call them visual clutter. You encounter one the moment you exit the security areas in the airport.
We were staying at Tsim Tsa Tshui. I went for a walk around 11pm on a weeknight. Most shops were closed as you would expect. Some were closing. A few of the gold shops were still open. When you come across a gold jewellery shop, you will see a cluster of them. Jewellery shops are a big business in Hong Kong.
I was coming back to the hotel after 11.30pm and I could still see attendants sitting inside one of the bigger gold shops.
