A man shows the "fruit" of 15 years of hard work – 20-centimeter-long fingernails – in Haikou city, South China's Hainan province, March 13, 2011.

The man surnamed Feng said he has been growing his fingernails for 15 years, and had once intended to apply for a Guinness World Record. However, he gave up after breaking his nails twice.

The longest one of the 4 fingernails exceeds 20 centimeters, and others grow either in a "spiral" or "scimitar" shape. [Photo/Asianewsphoto]
