What is the power of a smile？ You know what? I only know that.A smile is full of positive energy. It can make a frustrated person have a boiling passion.I Believe.A smile can work wonders. I still remember.Three years ago of a winter freezing. A more than 60 - year - old man saved a boy with his smile.The boy standing on the top floor almost jumped. An old man spent his drink. Young said don't stop him along much of his life Met with many setbacks already can't live.The old man said nothing Just smile always smile.Ji happened at this moment.Young looking back Rushed to the old man hugged him.A smile creates miracles﹗
