Hong Kong Island is noted for its juxtaposition of new and old.
Stained by pollution, and dotted with air conditioners and drying laundry, these bare, concrete boxes are ugly ... and yet fascinating.
Going inside isn't necessary; a taste of Hong Kong's past awaits you at street level. Buy a bun from the local bakery, or have tea at the chaan teng.
When you've had your fill, modern life is less than five minutes away.
