Jiuquan Tianbao Scenic Area (3) Seeing a group of eighteen Arhats wood carvings, took a watch

@ Jiuquan Tianbao Scenic Area (3)
I saw a group of eighteen Arhat wood carvings and patted the expression bag. The color is also a kind of level, after changing to monochrome, the distance is compressed. Enlarged the picture and was hit by their teeth. Does God Buddha brush their teeth sooner or later? Is their toothbrush electric (or mana-driven)?
