Experts have also unearthed two 2,000-year-old bronze lamps that can "swallow" smoke in the tomb of "Haihunhou".

The lamps are both in the shape of a goose catching a fish in its mouth. The light is attached to the fish. Smoke emitted during the burning of wax can enter the bird's body via an opening on the fish, travel through its neck and be dissolved by water stored in its hollow belly. The lamps can be dismantled for cleaning and have swinging lamp shades to adjust brightness.

It shows that Chinese lamp makers were coming up with designs to reduce air pollution as early as the Western Han Dynasty.
