It's normal to see beautiful carving designs on stones and woods.
But have you heard about carving on the light bulbs? Liu Yuhua, 66, lives in Yanhu District, Yuncheng City, northern China's Shanxi province.
He could carve plants like plum blossoms, orchid, bamboo and chrysanthemum on the thin glass bulb surface, using an electric drill. Meanwhile, he carved the four corresponding characters on the bottom of each bulb. "The glass of the light bulb is thin, and it's hard to carve on the surface.
It's slippery and easy to be broken. However hard it is, I want to reveal the artistic beauty of the work," Liu said. Liu also said that by doing so, he'd like to prove that the elders could also live a colorful life.
