...means that s/he make money by forming partners, or even "eating out" partners........

偏財 or 正財 is the original source of wealth! Not the way to make the money......I'm not quite so sure about this. Like Chien Ming Wang has neither
偏財 or 正財 and yet he got a sign-in bonus of 1.2 million us dollars in year 2000.
正財 is the wealth from career and jobs. 偏財 is the one from gambling, investment outside one's career and job.....Well, I've seen a lot of 8 words unorthodax to above. Bill gate, J.K. Rowling, and 李嘉誠 is quite enough to turn heads. Oh....I think 8 words you have on 李嘉誠 mandate justification.
I beg your pardon for not being direct because I have quite enough data to support or ratify on niether position. The best understanding I could share is 偏財 and 正財 is differ in nature, differ in how you access, and differ in how $ come to you.
