Changing lines (counted from the bottom): 5, 6.
What to read
Two changing lines: read both line texts of the original hexagram; the upper one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 4 蒙, line 6
擊蒙，不利為寇，利禦寇。
In the topmost line, undivided, we see one smiting the ignorant (youth). But no advantage will come from doing him an injury. Advantage would come from warding off injury from him.
Hexagram 4 蒙, line 5
童蒙，吉。
The fifth line, divided, shows its subject as a simple lad without experience. There will be good fortune.
The two hexagrams
Hexagram 4 蒙 — judgment
亨。匪我求童蒙，童蒙求我。初筮告，再三瀆，瀆則不告。利貞。
Măng (indicates that in the case which it presupposes) there will be progress and success. I do not (go and) seek the youthful and inexperienced, but he comes and seeks me. When he shows (the sincerity that marks) the first recourse to divination, I instruct him. If he apply a second and third time, that is troublesome; and I do not instruct the troublesome. There will be advantage in being firm and correct.
Hexagram 29 坎 — judgment
習坎：有孚，維心亨。行有尚。
Khan, here repeated, shows the possession of sincerity, through which the mind is. penetrating. Action (in accordance with this) will be of high value.
