2. Mathematical period: For a function f (x), if there is a non-zero constant T, so that when x takes every value in the domain, there is f (x + T) = f (x), then the function f (x) is called a periodic function. The nonzero constant T is called the period of this function.靠卖卤蛋为生的少女杜心羽（潘之琳饰）在送外卖时，全部卤蛋被玩世不恭的唐正浩Table同村和凌丰青梅竹马的大舌头阿兰（佘诗曼 饰）也来到香港谋生，得到凌丰关照在夜总会做清洁工。凌丰和金燕打赌如果她能培养出一个歌唱比赛冠军就斟茶认错，如果不能金燕则要退休。阿兰天生具有十分好的唱歌潜质，可惜她是大舌头，咬字不清。凌丰用计骗了金燕收阿兰做徒弟，等着下一届唱歌比赛时看她出丑。凌丰、金燕这对母子冤家能否最终相认？《破茧记之中二校园》由开心麻花魏翔导演，何欢、高海宝、东靖川、李宝儿、张卓行、具哈娜、房程程、张宵思等主演。讲述了一群来自天南海北的大一新生带着各自的梦想，在校园里上演一幕幕搞笑、离奇、浪漫而又温馨有趣的故事。郑老太太就不言语了，这确实是个法子。From basic skills to methodology to character and mode of thinking, it is a process from "skill" to "Tao". However, unfortunately, many people blindly worship "Tao" and despise "Shu", but they do not know that the real Tao comes from the accumulation of Shu and the natural process from quantitative change to qualitative change. Without solid basic skills and systematic methodology, it is ignorant and opportunistic to talk about the so-called "philosophy, art and character" and rely on beautiful words and high-profile rhetoric to attract attention. Experience does not necessarily translate into theory, and scattered knowledge points do not necessarily rise to system integration. However, due to the lack of basic foundation and knowledge accumulation, the so-called "investment philosophy" can only be a joke. "Avenue to Jane" and "Avenue to Connect" are logically reasonable, because there are only a few great principles after high abstraction, but the difference between "technique" is very large because it is very meticulous. Therefore, what really troubles people is the process of combining and refining from art to Tao.
