HANOI, May 29 (Xinhua) -- "Anyone want to sell their long hair?" came a sweet feminine voice creeping through a summer noon in the outskirts of Vietnam's Hanoi capital city.

The voice was not coming from the mouth of any woman or man, however, but from a small loud speaker attached to an old motorbike ridden by a middle-aged woman in the rural district of Thanh Tri.
