The Wolf (Tan Lang, 贪狼) in the Self palace (Ming Gong, 命宫)

What the classic says, Zi Wei Dou Shu Quan Shu (紫微斗数全书), volume two

Well placed, tall and heavy-set; badly placed, small in build, high-voiced and large in appetite. The temper is not constant, the mind full of calculation, quick to act and impatient of sitting still — clever moves that turn clumsy; fond of gambling, wine and company. In the four Tomb (墓) palaces (辰戌丑未) blessing runs thick, and with the Flare (火星) in accord it is genuinely fortunate, a name heard at a distance. With the Blade (擎羊) in the seat of the self and the Millstone (陀罗) and malefics compounding, hard straits; with the Iron (武曲), the Disruptor (破军), the Mystic (廉贞), the General (七杀) or the Void and the Plunder (空劫), a trade learned to keep body and soul together. In a woman's chart in the four Tomb palaces, and with the two Aides (左右), honoured: means enough, good for her husband, firm in character and large in aim.

贪狼属木，化桃花杀。贪狼入庙长耸肥胖，陷宫形小声高而量大，性格不常，心多计较，作事急速不耐静，作巧反拙，好赌博花酒。贪狼入男命吉凶诀：四墓宫中福气浓，提兵指日立边功，火星拱会诚为贵，名震诸夷定有封。贪狼守命擎羊逢，陀杀交加必困穷，武破廉贞同杀劫，百艺防身度岁终。贪狼入女命吉凶诀：四墓宫中多吉利，更逢左右方为贵，禄财丰富旺夫君，性格刚强多志气。贪狼陷地女非祥，衣食虽丰也不良，贪狼入限吉凶诀：北斗贪狼入限来，若还入庙事和谐，科权仕路多成就，必主当年发横财。贪狼主限四墓临，更喜人生四墓生，若见火星多横发，自然富贵冠乡邻。贪狼破军居陷地，遇吉化忌终不利，加杀照命无眠睡。

Part of this clause fixes a woman’s outcome by her sex; it is left out here, in the Chinese as well as the English, as everywhere on this site.

“Well placed” and “badly placed” refer to the star’s brightness in the branch the palace falls on: the same star in the same palace reads differently bright and dim, and the clause says how.

How this placement actually turns up

• Well placed (exalted or strong) in 49% of those charts, badly placed (fallen) in 17%, in between the rest.
• Alone in the palace in 50%; sharing it with The Emperor (紫微) 17%, The Mystic (廉贞) 17%, The Iron (武曲) 16%.
• Carries a birth-year transformation in 30%: Fortune (化禄) 11%, Power (化权) 8%, Trouble (化忌) 11%.
• How often the conditions the classic’s line names actually occur — one of the four difficult stars (擎羊陀罗火星铃星) in the palace with it: 31%; Earth Void or Earth Robbery (地空地劫) with it: 15%; one of the six helper stars (左辅右弼文昌文曲天魁天钺) with it: 40%; Lu Cun (禄存) with it: 8%.

Counted by casting every day from 1950 to 2009 at each of the twelve hours — 262,980 charts, 8.3% of which have The Wolf here (every main star sits in every palace in about one chart in twelve). A count, not a reading.
