Quadruplets have hair cut into shapes of numbers showing the order of birth

Quadruplets brothers had their hair cut in different styles to be easily identified in school in South China's Shenzhen city.  

Since the quadruplets went to the same primary school, Tan Chaoyun, the mother of the quadruplets, came out with the idea of using special hairstyle to make the bothers easy to be identified. The bothers' hairs were cut into shapes of numbers showing the order of birth.  

"Since the quadruplets are too similar in their looks, manners, smiles and voices, we cannot differentiate them, and thus we arranged them in four different classes after we got their parents' agreement," said the director of the moral education office of Shangwu Primary School.  

The quadruplets were born in 2006 and Tan was an older mother then. A lot of media reported the rare quadruplet birth.
