喜笑皆属心火，盖火得风而焰，笑之象也。古人治一男笑不休，口角流涎，用黄连
解毒汤，加半夏、竹叶、竹沥、姜汁而愈。一妇笑不休，用温盐汤，探吐出热痰五升而
愈。怒者，乃阴气盛而闭遏其阳，则不得伸越而发也。丹溪治善怒方，香附（细末）六
两，白汤每服五钱，此疏肝快气之义也。然有心肾之阴不足，而遇事易烦发怒者，又宜
滋肝阴心血，而非香燥疏肝快郁之药所宜也。
司天主上半年六个月，在泉主下半年六个月。
子午（少阴君火司天，阳明燥金在泉。）
卯酉（阳明燥金司天，少阴君火在泉。）
辰戌（太阳寒水司天，太阴湿土在泉。）
丑未（太阴湿土司天，太阳寒水在泉。）
寅申（少阳相火司天，厥阴风水在泉。）
已亥（厥阴风木司天，少阳相火在泉。）
歌诀曰∶子午少阴君火天，阳明燥金应在泉，丑未太阴湿土上，太阳寒水两连绵，
寅申少阳相火旺，厥阴风木地中联，卯酉却与子午倒，辰戌巳亥亦皆然。
凡应天为天符，如木运之岁上见厥阴，火运之岁上见少阴、少阳，土运之岁上见太
阴，金运之岁上见阳明，水运之岁上见太阳。盖此五者，司天与运气相会，天气下
降，如合符运，故名天符。更凡永岁为岁，直如木运之岁，岁当亥卯；火运之岁，岁当
寅午；土运之岁，岁当辰戊丑未；金运之岁，岁当巳酉；水运之岁，岁当申子。此五
者，岁之所直，故曰承岁，为岁直。更凡火运之岁，上见少阴，年辰临午；土运之岁，
上见太阴，年辰临丑未；金运之岁，上见阳明，年辰临酉。此三者，乃天气运气，与年
辰俱会，故云三合为治。然岁直又为岁位，三合亦为天符，《六微旨大论》曰∶天符岁
会，曰太一天符，谓天运与岁俱会也。凡天符中之已丑已未戊午乙酉，岁会中之戊午已
丑巳未乙酉，皆天符岁会相同，并名曰太一天符也。太一者，至尊无二之称也。三者分
之贵贱，则天符之岁，犹之执法之臣，法不可假，故邪中执法，其病速而危。如戊子
日，戊为火运，子为火气，亦是天符，此日得病者因半岁会之岁，犹之行令之臣，当有
主之者在，故邪中行令，其病徐而持。如甲辰，甲为土运，辰为土支，乃岁会也，年月
日时，同太一天符之岁，犹之君主之贵人也，故邪中贵人者。其病暴而死。如戊午
日，戊为火运，午为火支，又为火气，即太一天符，此日病者死。
喜和笑都属于心火的表现，因为火遇到风就会燃烧，这正是笑的象征。古人曾治疗一个不停发笑的男子，他嘴角流涎水，医生使用黄连解毒汤，加入半夏、竹叶、竹沥和姜汁，最终治愈了他。又有一位不停发笑的女子，医生用温盐水催吐，吐出五升热痰后痊愈。怒这种情绪，是由于阴气过盛而闭阻了阳气，导致阳气无法舒展发泄而产生的。朱丹溪治疗易怒的方子，是用香附（研成细末）六两，每次用白开水送服五钱，这是疏肝理气的含义。然而，如果是由于心肾之阴不足，遇到事情容易烦躁发怒的人，又应当滋补肝阴和心血，而不适合使用香燥类疏肝解郁的药物。
司天主管上半年的六个月，在泉主管下半年的六个月。
子年和午年（少阴君火司天，阳明燥金在泉。）
卯年和酉年（阳明燥金司天，少阴君火在泉。）
辰年和戌年（太阳寒水司天，太阴湿土在泉。）
丑年和未年（太阴湿土司天，太阳寒水在泉。）
寅年和申年（少阳相火司天，厥阴风水在泉。）
巳年和亥年（厥阴风木司天，少阳相火在泉。）
歌诀说：子午年是少阴君火司天，阳明燥金应在在泉之位；丑未年是太阴湿土司天，太阳寒水在在泉之位连绵不断；寅申年少阳相火旺盛，厥阴风木在在泉之位相连；卯酉年的情况与子午年相反，辰戌年和巳亥年也是如此。
凡是运气与司天之气相符的称为“天符”，比如木运之年遇上厥阴风木司天，火运之年遇上少阴君火或少阳相火司天，土运之年遇上太阴湿土司天，金运之年遇上阳明燥金司天，水运之年遇上太阳寒水司天。因为这五种情况，司天之气与岁运相会合，天气下降，如同符合符契一样，所以叫作天符。另外，凡是统管一年的年份称为“岁直”，比如木运之年，年份对应亥、卯；火运之年，年份对应寅、午；土运之年，年份对应辰、戌、丑、未；金运之年，年份对应巳、酉；水运之年，年份对应申、子。这五种情况是年份所直接对应的，所以叫作“承岁”，即岁直。另外，凡是火运之年，上面见到少阴君火，年份地支临午；土运之年，上面见到太阴湿土，年份地支临丑或未；金运之年，上面见到阳明燥金，年份地支临酉。这三种情况，是天气、岁运与年份地支三者相会合，所以叫作“三合为治”。然而岁直也称为岁位，三合也属于天符，《六微旨大论》说：天符和岁会相会的年份，称为“太一天符”，意思是天运与岁会相会合。在天符中的己丑、己未、戊午、乙酉年，以及岁会中的戊午、己丑、己未、乙酉年，都是天符和岁会相同，都命名为太一天符。“太一”是至尊无二的称呼。如果从这三者的贵贱来区分，那么天符之年，就像执法的大臣，法律不可假借，所以邪气中伤执法之臣，发病迅速且危险。比如戊子日，戊代表火运，子代表火气，这也是天符，这一天得病是因为遇到了半岁会之年，就像执行命令的大臣，因为有主宰者在，所以邪气中伤行令之臣，发病缓慢且持久。比如甲辰年，甲代表土运，辰代表土支，这是岁会，年月日时如果遇到太一天符之年，就像君主或贵人，所以邪气中伤贵人，发病暴烈且致死。比如戊午日，戊代表火运，午代表火支，又是火气，就是太一天符，这一天生病的人会死亡。
Joy and laughter both belong to the Fire of the Heart. This is because fire flares up when it meets wind, which is the image of laughter. In ancient times, a man who laughed incessantly with saliva flowing from the corners of his mouth was cured using Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) added with Banxia (Pinelliae Rhizoma), Zhuye (Bambusae Folium), Zhuli (Bambusa Sap), and Jiangzhi (Zingiberis汁). A woman who laughed incessantly was cured by inducing vomiting with warm salt water, expelling five sheng (a traditional unit of volume) of hot phlegm. Anger arises when Yin Qi (Yin Energy) is excessive and obstructs Yang Qi (Yang Energy), preventing it from extending and venting outward. Zhu Danxi’s prescription for treating chronic anger consists of Xiangfu (Cyperi Rhizoma) ground into fine powder, six liang, taken five qian each time with plain boiled water; this embodies the principle of soothing the Liver and promoting the free flow of Qi. However, for those whose anger and irritability are triggered by events due to insufficiency of Yin in the Heart and Kidney, it is appropriate to nourish Liver Yin and Heart Blood, rather than using acrid-warm herbs that soothe the Liver and resolve stagnation.
Si Tian (Heavenly Ruler) governs the first half of the year (six months), while Zai Quan (Earthly Spring) governs the second half of the year (six months).
Zi and Wu years: Shaoyin Junhuo (Lesser Yin Sovereign Fire) is Si Tian, Yangming Zaojin (Greater Yang Dry Metal) is Zai Quan.
Mao and You years: Yangming Zaojin (Greater Yang Dry Metal) is Si Tian, Shaoyin Junhuo (Lesser Yin Sovereign Fire) is Zai Quan.
Chen and Xu years: Taiyang Hanshui (Greater Cold Water) is Si Tian, Taiyin Shitu (Greater Yin Damp Earth) is Zai Quan.
Chou and Wei years: Taiyin Shitu (Greater Yin Damp Earth) is Si Tian, Taiyang Hanshui (Greater Cold Water) is Zai Quan.
Yin and Shen years: Shaoyang Xianghuo (Lesser Minister Fire) is Si Tian, Jueyin Fengshui (Extreme Yin Wind-Water) is Zai Quan.
Si and Hai years: Jueyin Fengmu (Extreme Yin Wind-Wood) is Si Tian, Shaoyang Xianghuo (Lesser Minister Fire) is Zai Quan.
The rhyme states: Zi and Wu years have Shaoyin Junhuo as Si Tian, Yangming Zaojin should be Zai Quan; Chou and Wei years have Taiyin Shitu above, Taiyang Hanshui connects continuously below; Yin and Shen years see Shaoyang Xianghuo flourishing, Jueyin Fengmu links in the earth; Mao and You are inverted relative to Zi and Wu, while Chen-Xu and Si-Hai follow the same pattern.
Whenever the Yearly Movement (Yun) coincides with Si Tian, it is called "Tian Fu" (Heavenly符/Concordance). For example, in a Wood Yun year where Jueyin Fengmu is Si Tian; in a Fire Yun year where Shaoyin Junhuo or Shaoyang Xianghuo is Si Tian; in an Earth Yun year where Taiyin Shitu is Si Tian; in a Metal Yun year where Yangming Zaojin is Si Tian; in a Water Yun year where Taiyang Hanshui is Si Tian. Because in these five cases, Si Tian and Yun meet, Heaven's Qi descends, matching like a tally, hence named Tian Fu. Furthermore, the year directly governed by Yun is called "Sui Zhi" (Year Direct). For instance, in a Wood Yun year, the year corresponds to Hai, Mao; in a Fire Yun year, to Yin, Wu; in an Earth Yun year, to Chen, Xu, Chou, Wei; in a Metal Yun year, to Si, You; in a Water Yun year, to Shen, Zi. These five correspondences are what the year directly holds, thus called Cheng Sui, or Sui Zhi. Additionally, in a Fire Yun year, if Shaoyin Junhuo appears above and the year branch is Wu; in an Earth Yun year, if Taiyin Shitu appears above and the year branch is Chou or Wei; in a Metal Yun year, if Yangming Zaojin appears above and the year branch is You. These three cases represent the convergence of Heavenly Qi, Yun, and the Year Branch, hence called "San He Wei Zhi" (Three Harmonies for Governance). However, Sui Zhi is also called Sui Wei, and San He is also considered Tian Fu. The *Liu Wei Zhi Da Lun* states: When Tian Fu and Sui Hui (Year Assembly) coincide, it is called "Tai Yi Tian Fu" (Supreme One Heavenly Concordance), meaning Heavenly Yun and Sui Hui meet. Among Tian Fu years, Ji-Chou, Ji-Wei, Wu-Wu, and Yi-You; and among Sui Hui years, Wu-Wu, Ji-Chou, Ji-Wei, and Yi-You, all share identical Tian Fu and Sui Hui attributes, collectively named Tai Yi Tian Fu. "Tai Yi" denotes supreme uniqueness without rival. Differentiating their hierarchy: Tian Fu years are like ministers enforcing law; since law cannot be compromised, when pathogenic factors strike such ministers, the disease is rapid and critical. For example, on Wu-Zi day, Wu represents Fire Yun and Zi represents Fire Qi, constituting Tian Fu. Illness contracted on this day, influenced by the semi-year assembly, resembles ministers executing orders under authority; thus, when pathogens strike executors, the disease is slow and persistent. For example, in Jia-Chen year, Jia represents Earth Yun and Chen represents Earth Branch, constituting Sui Hui. If Year, Month, Day, and Hour align with Tai Yi Tian Fu years, it is akin to encountering noble lords or rulers; thus, when pathogens strike nobility, the disease is sudden and fatal. For instance, on Wu-Wu day, Wu represents Fire Yun, Wu represents Fire Branch and Fire Qi, forming Tai Yi Tian Fu; illness contracted on this day leads to death.
