Hi divinely,
I've been reading about duan zhang as well, because same as you, i too have it on both palms and i'm female.
On the internet, this floats around as ke fu ke mu, and also ke husband if female.
I'm curious as how this affects me in my life, or whether it did affect my parents and my current relationship life. (People have said "oh how unfortunate you are female! Would have been wonderful if you are male!"

)
Don't really know how true are these at this day and modern society, where females are able to be strong-charactered and have their own careers as well. Somehow I've thought they might apply in the olden days, because women were not well-liked to be strong.
Read some articles online, that the percentage/probability of duan zhang appearing on down syndrome people is higher.
Yet again, there are high-career flyers such as MM Lee with duan zhang as well.
I've also read that usually duan zhang is hereditary, that means it could come from either parent. I've checked some of my family members palms, some of them do have duan zhang but only on 1 hand. Again, internet stuffs say that duan zhang on 1 hand is more difficult to manage as compared to both hands, because when it appears on both hands, there is some sort of 'balance' brought about to the character.
Sorry for reviving such an old topic again...
