When　we　think　about　freedom,it's　not　only　those　locked　behind　bars　who　lost　their　freedom.Even　us　although　be　able　to　walk　around　freely,we　are　still　in　a　way　locked　up　inside　a　kind　of　jail.
That　is　why　a　Zen　master　by　the　name　of　Wu　Man,he　once　said　that,"There　are　flowers　in　spring　and　the　cool　moon　in　Autumn.There　are　also　cool　breezes　in　summer　and　snow　in　winter.Once,there're　no　longer　any　trivial　matters　trapped　inside　your　heart.You'll　be　living　in　the　best　moment　in　your　life."
