SMTH says:
如申子辰，申乃子之母，辰乃子之子，申乃水生，子乃水旺, 辰乃水气，生即产，旺即成，库即收，有生有成有收，万物得始得终，乃自然之理，故申子辰为水局。
Like Shen Zi Chen, Shen is the mother of Zi, Chen is the child of Zi, Shen is where water is born, Zi is where water is prosperous, Chen is water Qi, to be born is to be produced, to be prosperous is to be successful, storage means to be stored. There's production, success and storage. Ten thousand beings has beginning and the end, it's the natural law. Thus Shen Zi Chen is water frame.
若三字缺一则化不成局，不可以三合化局论。
If among the three words, one is missing, the transformed frame would not be successful, it cannot be regarded as the structure 3 combinations.
盖天地间道理，两则化，一阴一阳之谓也，三则化，三生万物之谓也。
It's the natural law, 2 to be transformed has to be one Yang and one Yin, 3 to be transformed is because 3 engenders ten thousand beings
已酉丑、寅午戌、亥卯未皆然。Si You Chou, Yin Wu Xu, Hai Mao Wei are all like this.
五行不言土者，四行皆赖土成局，万物皆归藏于土故也；若辰戌丑未全自作土局论。
The five elements are not including Earth, all the other four elements rely on earth to establish a transformed frame, that is because ten thousand beings return to earth (at some point). If there's Chen Xu Chou Wei all complete, it's regarded as an earth structure.
凡命有合，要得局为佳。假令丙丁生人见亥卯未印、已酉丑财为得局，见寅午戌火为本局，申子辰水为官局，辰戌丑未土为伤局。
Should there be combination in the natal chart, it has to have a frame to be regarded as good. For example, a Bing or Ding person sees Hai Mao Wei as 'Seal', Si You Chou as 'Wealth', Yin Wu Xu as its own frame, Shen Zi Chen as 'Officer' structure, Chen Xu Chou Wei as the 'Hurting' structure.
又如丙人见已酉丑，丁人见寅午戌为三位禄格，谓丙以已为禄，丁以午为禄，酉丑合已，寅戌合午故也。《珞??录子》云："禄有三会"。《壶中子》云："得一分三，折月中之仙桂"。此之谓也。余仿此例。
And also if Bing person sees Si You Chou, Ding person sees Yin Wu Xu, it's regarded as three-prosperity -structure, as Si is the 'Lu' of Bing, Wu as the Lu of Ding, You Chou combines with Si, Yin Xu combines with Wu. <LuoLu Zi> says: 'Lu' has three meetings. <Hu Zhong Zi> says: to have one but divided into three, reduces the auspiciousness in the month (EB). It's talking about this, the other (elements) are all like this.
