Meet Jiang Yunlong, Jiang Yunxiao, Jiang Yunhan And Jiang Yunlin,

the problem if you have not already guessed,

is that the quads are so alike not only their teachers can not tell them apart their parents can not too! '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', I guess the magic marker will also have been out, can you imagine the squabbles over books, toys and bikes, still it will only be a matter of time before the PC brigade wade in and say it 'de-huminises' the kids!
