Alicia Tan reports on an online "challenge" trend in China in which women prove that the have a thin waist by covering it completely with a sheet of office paper.
For the challenge, women are required to take photos of themselves with a piece of A4 printer paper in front of their waists.
The width of an A4 paper is eight inches, and women are trying to prove that their waistlines are narrower than that.
The A4 waist challenge started in China around February and has seen hordes of Chinese women taking to their Weibo accounts to show off their trim waistlines.
