1. 大纲和细目。 ??

汉 徐干 《中论·民数》∶“是以先王制六乡六遂之法，所以维持其民而为之纲目也。”《南史·文学传·锺嵘》∶“时 齐明帝 躬亲细务，纲目亦密。” 宋 司马光 《乞令校定所写稽古录札子》∶“顾以年祀悠远，载籍浩博，非一日二日所能徧阅而周知∶所宜提其纲目，撮其精英，然后可以见治乱存亡之大略也。” 明 汪道昆 《洛水悲》∶“部中更有一段新词，名《洛神记》，小子略陈纲目，大家齐按宫商。”

I have read dictionaries over and over, which is against my plan of quick finishing but also necessary to avoid error at this stage.
If absorb the essence of I-Ching, I should limit my words to minimum, 精华 vs. 糟粕 does not comparable to 大纲 vs. 细目, but it implies by deep thought, which is the advantage of Chinese character. also compare 华 with日.

This directs me to delete as many as possible those details in my first book, which should be concise instead of all-inclucive, reductive instead of redundant.
