West and East groups. Chinese verse English horoscopes

Sorry hor. All those born in the year of the horse whom I know don't really get along well with me tiger. And after calculating their kua no. They all belong to the West group and I belong to the East hence don't get along. I think they can get along with West group only. And after having many friends, I realize English horoscope is more accurate cos I have friend born in the year of Monkey we get along so well cos she is Leo and I am Aries. According Chinese horoscope monkey don't get along with tiger and besides she is also west group. Pls explain
