Temples temples everywhere

In the midst of the city are wonderful contrasts. Standing in the bustle of Central on Queens Road, flanked by banks and international boutiques, it’s easy to forget that China exists just up that side street or along the next alley. Except for the people of course. At lunchtime the offices empty into a sea of dark heads flowing slowly along the sidewalk, broken up only occasionally by blond tresses.

Many shops have tiny shrines in front, festooned in red with incense burning. And many shop windows have a little glass of water in them. Why? Do spirits get thirsty? Anyone know?
