Pei Haozheng from Huazhong Agricultural University amazed audience by his paper art works. The 21-year-old started to learn origami at 11. Now he has won a bronze prize at the International Origami Internet Olympiad.

He said although the art looks easy, it is extremely difficult, especially to create new paper works.

"It often takes several days to finish a work, but the designing part can take a month or longer," Pei said.
