Specific pattern: a place is surrounded by mountains, and the mountains are undulating and endless. The peaks rise slowly from west to east, long but not thin, thick but not swollen, with light posture, easy to retract and unhurried, and crawl down from north to south calmly and smartly. Venus opens the account, Qinglong White Tiger Shashou is heavily guarded, Qinglong commits crimes, and all levels at the foot of the mountain are on guard. The mountains are high and the halls are vast.
From Ding Xuanxue's "Death Blows":
When you enter the Heavenly Palace at noon at midnight, you must not encounter ugliness.
Call five thunder hit people, the first five and the last five should know.
