When was the last time you gave or received a hug? Do your parents hug you before you go to school? In Western countries, it is quite common to greet close friends or relatives with a hug.
You might hug your teammates after winning a basketball game. If one of your friends is having a bad day, you can hug him to cheer him up. Friends who haven't seen each other for a long time will usually hug each other when meeting.
Of course, people in different countries have different opinions about hugging. After coming to China, I've noticed that Chinese people are generally more reluctant (不情愿的) to hug than those are in my home country, the USA.
My Chinese friends told me that hugging is considered to be very intimate (亲密的) in their culture. It usually only happens between people who are really close to each other, like couples. Chinese people don't usually hug in public either.
But people's attitudes towards hugging can also change. I remember watching a video story about a "hugging party" that was held in Shanghai. A local artist held the party, inviting strangers and asking them to hug each other.
The Chinese participants clearly looked uncomfortable. However, after the party, several of them changed their minds. They decided that hugging doesn't have to be awkward (尴尬的) and can actually be quite nice. So next time you see your mum or dad, give her or him a hug—see how it makes you feel.
