Nowadays，kuakuaqun or praise groups have become more and more popular on the Internet，Their aim is to comfort young people.These groups provide words of support for those who are unhappy.

Spending just a little money，you can enter such a group.Share your problems or success，and you will receive positive messages soon.These messages，mostly from strangers，will help you feel better.A leader of one of the groups talks about his first purpose，"I want to help people learn to praise others and accept others，praise."

I like the idea of kuakuaqun.However，I think getting praise from strangers online isn't very useful in the long run.This is especially true when you are paying for the praise.These people don't know you，so the praise may not be earnest.Real and meaningful praise comes from the people you know.

With this in mind，we should try to praise our friends and family members when they need some encouragement.Simply saying to a classmate， 'I like you'，can lift his or her confidence.Being kind to others is easy.And it adds the necessary sweetness to make everyone's life better.
