The six-year-old boys received the extreme haircut ahead of their first day of school in Shenzhen, located in south China’s Guangdong province, UK Metro reported

Their parents decided to mark them with 1, 2, 3, 4 on their heads to make it easier for teachers and classmates to tell them apart.
The boys, named Jiang Yunlong, Jiang Yunxiao, Jiang Yunhan and Jiang Yunlin, are so alike that their parents even struggle to tell the difference.
‘My sons are identical, even to me,’ the boys’ mother Tan Chaoyun told local media.
She added: ‘Even now, their father can’t tell which one is which.
‘Sometimes, he punishes the second one for something the third one has done.’
The boys won’t be able to get away with shifting the blame for much longer  however with their new easily identifiable haircuts.
‘Teachers and classmates can’t get confused with the big marks on their head,’ their mother added.
With their strong head for figures, maths class is likely to be a breeze for these boys.
