In recent weeks , small groups of young people appeared on downtown sidewalks in Changsha, Beijing and other cities , holding signs with the words "free hugs ,and offered embraces to any passer-by who would care for one. "
Calling themselves " the hug league" ,they said they were inspired an international news story of a similar type and intended to promote human contact in the face of growing alienation(疏远）in urban china.
We Chinese ,contrary to what is shown in our love movies and television shows , rarely run into each other's arms and cry our hearts out .We are raised in a culture of emotional restraint(克制）。We mark our meetings and departures with a wave of hand and  a handshake of light touch . Not so long ago , even young lovers hugging in public places were considered rude.
But that doesn't mean we are immune(免疫的）to the wonderful feeling of human tactility(触感）。I remember my mother was visibly moved when I hold her hand for the first time while walking her across a busy street in the U.S. The circumstance made it more natural .But cultures don't evolve overnight ."It's hard to get rid of the old belief that man and woman shouldn't have any physical contact ,"some explained .In the late 1970s some feared that social dance would lead to sexual (侵扰）.But the awkwardness was overcome as more and more people came to accept dancing with partners who were not their spouses (配偶）as a perfectly normal form of recreation.
In this environment of changing social customs manners , how people act could be the working many factors ,including their personality.Some offer bear hugs to everyone they know while others would shiver at the thought of medical personnel touching them with a stethoscope(听诊器）。The line between proper and improper often shifts(移动）with the sands of circumstances.
Offering hugs to strangers on the street is too radical(激进的）a step to have any meaningful impact on our customs.If anything , the huggers should start with their loved ones.
