Guangdong brick-carving is very special (unique) in its technique of making. Different parts of a picture are carved separately on small pieces of ready-made fired bricks before they are laid onto a wall to form a whole picture, whereas those of other provinces are made by carving a whole picture on a big piece of unburned brick before it is fired and put onto the wall. So Guangdong brick-carving needs much more precision and skill and is finer (more exquisite) and is of greater artistic value
