Changing lines (counted from the bottom): 2, 3, 4, 5.
What to read
Four changing lines: read the two unchanged lines of the resulting hexagram; the lower one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 12 否, line 1
拔茅茹以其彙，貞吉。亨。
The first line, divided, suggests the idea of grass pulled up, and bringing with it other stalks with whose roots it is connected. With firm correctness (on the part of its subject), there will be good fortune and progress.
Hexagram 12 否, line 6
傾否，先否後喜。
The sixth line, undivided, shows the overthrow (and removal of) the condition of distress and obstruction. Before this there was that condition. Hereafter there will be joy.
The two hexagrams
Hexagram 18 蠱 — judgment
元亨。利涉大川。先甲三日，後甲三日。
Kû indicates great progress and success (to him who deals properly with the condition represented by it). There will be advantage in (efforts like that of) crossing the great stream. (He should weigh well, however, the events of) three days before the turning point, and those (to be done) three days after it.
Hexagram 12 否 — judgment
否之匪人，不利君子貞，大往小來。
In Phî there is the want of good understanding between the (different classes of) men, and its indication is unfavourable to the firm and correct course of the superior man. We see in it the great gone and the little come.
