Author's name of bamboo carving fan bone

As for the names of painters and calligraphers who carved bamboo fan bones, painters and calligraphers (especially well-known painters and calligraphers) always carved their names on the fan bones (such as "Imitation Foot Platform" and Wang He applied for "1932 Summer", etc.), while some bamboo sculptors hid their names or published them on another fan bone. Therefore, when appreciating handicrafts such as carved bamboo, we must make a concrete analysis and textual research on the names on the utensils. If you can't see the name of the painter, you think the painter must be good at carving bamboo, too; When I saw the name of the bamboo sculptor (including the seal), I thought the paintings and calligraphy on the objects must be his creation.
