只要向你旁边的人简单地说声“你好”或者“嗨”，然后对他们报以微笑，那么你的心情马上就会好起来。

Just saying a simple "Hello" or "Hi" to the person next to you, and offering them a smile, could give you an instant mood-boost.

如果你笑着对别人说你好，他们也会反过来把笑容传递给他们看到的其他人。

If you smile at someone and say hi, they may in turn follow by smiling at everyone else they see.
