丑到爆:您见过比这还丑的脸么

This is a face only a mother could love,but from now on you should have no trouble putting a name to it.Tang Shuquan,43,may appear very,very ugly in these pictures but his look has won him the Guinness World Record for making the most twisted face.

And now, he's launched a challenge to the public to see if anyone out there can match him.

Tang has offered a 100,000 yuan ($10,250) reward to anyone who can defeat him in a face-off to find the ugliest.

Tang, from Chengdu City, Sichuan province, China, says he's the world's foremost gurning expert and no-one can match him.

He perfected his art for seven years to create the most screwed up face possible before unleashing his unique talent on the world 10 years ago.

In March he took part in an Italian Guinness World Records TV show on the country's Channel 5 and yesterday was awarded $10,000 in prize money and a Guinness medal.
