Rent-a-grave

Why is there so much empty space at Chai Wan Cemetery? Isn’t it supposed to be overcrowded just like other cemeteries in Hong Kong?

It turns out many of the grave plots are only rented, not sold. Every ten years the remains are dug up. And the space is then rented to somebody else. Hence the temporarily unoccupied plots.

It is really not such a bad idea. If every dead person has to occupy a plot, sooner or later space will run out. And two or three generations later, chances are that there will not be anyone around to pay their respects. What is the point of keeping the grave and the remains?
