undiao literally means Cloud-carving. It refers to a technique
where an item is painted with colors in layers, and then a pattern is
cut into it with a V-shaped blade, so the colors of the different
layers are exposed, like looking at the walls of the Grand Canyon. In
China it is also sometimes referred as tixi, and in Japan,
where they learned the technique from China, it is called guri.
(if you are looking for more examples on the web the most common
search term is guri)
Though looking at a yundiao you can count 7 or 8 layers, there are actually many more than that. Because of the thinness with which lacquer must be applied, there are usually several dozen, from 60 to 100, layers of lacquer required to get the necessary thickness for the carving to be done. Each layer of red or black that you see consists of 8 or 10 actual layers of lacquer, each of which must be applied, fully dried, and sanded before the next one can be done. This requires months of preparation before the actual carving can be begun.
