Leung Ho Shui-tin

From waxing to electrical epilation and laser surgery, getting rid of unwanted hair is big business. But amid all these new-fangled methods, Leung Ho Shui-tin, aka Mrs Leung, is determined to keep the tradition of threading—removing single hairs with a length of cotton thread—alive. She talks to Samuel Lai about the ancient practice, which has been alive in China for thousands of years.
