Hence it is a subject of inquiry which can on no account be neglected. Therefore, the classics are based on five (things), and the schools are based on their plans, and their feelings are asked: one is Tao, the other is heaven, the third is earth, the fourth is generals, and the fifth is law. The Tao makes the people and the people agree, so they can (to) die with it, and they can (to) live with it, instead of (fear of danger) (paradox). Heaven signifies night and day, cold and heat, times and seasons. Earth comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death. The Commander stands for the virtues of wisdom, sincerely, benevolence, courage and strictness. Dharma, music system, official way, the main use also. All these five will be heard, those who know will win, and those who do not know will be defeated.围绕广州名茶楼之一的天然居少东周敬文（陈庭威 饰），邂逅在天然居卖唱的歌女（王馨平 饰），在街上认识刚从顺德农村来穗工作的陈炳（欧锦棠 饰），此君生性行侠仗义，并在天然居内工作，与男扮女装的天然居侍应李阿弟（文颂娴 饰）结为兄弟。周敬文一次北上韶关，却在铁路上遇上山贼（李树楷 饰），但同班列车却有当时广东军阀冯某之子（袁文杰 饰），广州当局因而很快剿灭该党山贼，而周冯则结为好兄弟。冯军阀的副官程忠（刘锡贤 饰）乃系广州大奸大恶之徒，陈炳得罪程某，因而被他诬为山贼同党，与李树楷等山贼一同被处决，后得冯少帅所救，而程忠则怀恨在心。却遭逢日本侵华，程忠勾结日伪，成为汉奸，将军阀冯某杀死，冯少帅因而改旗易帜，效忠重庆政府，此时敬文幼弟敬业（杜汶泽 饰）在损友唆使下，促长兄分家，天然居因而易手，而天然居内诸人均各散东西。广州沦陷，周敬文却挆降日本，成为广州伪政府维持会成员，但暗里却是从事救助广州同胞，天然居易手后北上从军的陈炳、冯少帅等人，均欲暗杀周敬文，后来真相大白，心结解除。而周敬文则在广州城内开办“天然豆品居”，制作豆品解救同胞之脚气病。保险员大岛的工作是向客户推销生命保险，有一天，他突然能看见人死前的最后一刻，大岛决定利用自己的力量帮助这些人。（伊東四朗、島かおり饰）Beijing曾经在大学时代拥有辉煌战绩的＂飓风＂篮球队的队长浩南欲说服早已解散的球队队友重出江湖参加全国篮球争霸赛，但队友已经完全不复当年意气风发的冠军状态。要带领这几个独臂清洁工，精神失常者，植物人，种菜大叔重新开始训练，走出阴霾，完成一次不可能的比赛。于是浩南说服队友出赛的过程变成了一场千奇百怪的搞笑之旅，而就是这么一帮完全没有希望夺冠的人，最终他们是否能够重新振作，投入训练和比赛呢？对于这类问题，他们自小被家人考问多次，最是熟练了，如今能回答的滴水不漏，一个亲人也不得罪。
