Lan diao is the ancient Chinese folk art of olive-pit carving, that consists of the skillful chiseling of olive pits into miniature carvings of historical themes and legends.

The artists takes advantage of the natural shape of the olive nut, which often led to the nut being carved into a boat.

Olive boat carvings can take any form and shape, from small fishing boats to pleasure boats and large dragon boats.

The carvings can be so elaborate, that any windows can be opened and closed with ease, whilst some boats have their flanks carved with inscriptions of prose and poetry.
