Keeping the smiling face not only means the person has the good character, but also means the person has the positive attitudes towards life.

People always say the one who likes smiling will never lack of luck. Indeed, the smiling people are friendly and kind, they like to give hands to other people and people like to make friends with them, so when the smiling people are in trouble, people around them will take no hesitation to help them. I have a friend who always has smile in his face, he seems to be never angry with others. All the guys like to talk to him and they are willing to help him. Keeping the smiling face not only means the person has the good personality, but also means the person has the positive attitudes towards life. 
人们总是说爱笑的人运气不会差。确实，微笑的人是友好并且善良的，他们喜欢帮助别人，人们也喜欢和他们交朋友，所以当微笑的人有困难的时候，在身边的人会毫不犹豫地帮助他们。我有一个朋友，脸上总是挂着笑容，他似乎从来不会和别人生气。所有的人都喜欢和他交流，并且交朋友。保持笑脸不仅意味着一个人有好的性格，也意味着这个人对生活有着乐观向上的态度。
