That was extraordinary Although I don't advocate cutting/harvesting long hair , it seemed to be done with reverence and respect.
I was in China last year. We were in a beautiful town called Guilin.
It is a custom there for women to grow their tresses VERY long. Group washings and communal hair care are common and encouraged . Needless to say. . . . . . . .I was in hair Heaven
PS , the closing shot in that film is of the skyline of Shanghai .
It's another unforgettable sight
