Micro-carving, also known as rice carving and fine carving, can be divided into tooth carving, bamboo carving and hair carving. This kind of carving is to carve poems and paintings on ivory pieces, bamboo pieces, rice grains or a few millimeters of hair, which is the most exquisite art in China's traditional arts and crafts.

Micro sculpture has a long history. On the Oracle Bone Inscriptions in the Western Zhou Dynasty, a miniature lettering of only 0.6 silk meters was found.

The production of micro-carving crafts requires artists to have a high level of calligraphy and skilled skills in using carving tools. When carving, you need to hold your breath and pay close attention, which has always been called "stunt".

Micro-carving technology is represented by Suzhou micro-carving. Suzhou Zhang Yuji's Poems of a night-mooring near maple bridge and Preface to the Lanting Pavilion are carved with ivory rice, with clear handwriting and vigorous brushwork, which is amazing.
