Kong Qingsi, a farmer from Zoucheng city of East China's Shandong Province, fell in love with engraving on stone when he was 20. Kong used to pick up a stone and practice his skill as long as he was free from farm work. Years of rigorous practice resulted in his excellence in the art. (Photos: VCG)

Two hammers, a pair of drills made from alloy steel and a light bulb,are his tools — simple instruments that demand patience and  precision. “The bulb will shatter if you use too much  force. Even though a crack is sometimes unnoticeable, it would compromise the quality of work,”said Kong.

To cut down cost, Kong buys used bulbs from recycling plants. He has also used welding to customize his own tools.

The 12 traditional Chinese Zodiac signs have complex contours. Kong has to engrave 6,000 strokes to finish one Zodiac pattern.

He has become famous as “the person who engraves most Zodiac patterns on one light bulb with an iron hammer”. Kong has started a workroom at a scenic place near his hometown to showcase skills and his work to tourists.
