Palmistry has its roots in Indian and Chinese astrology as well as Romani (Roma/ Gypsy) fortune-telling. The Romani are Indo-Aryans originally from northern India. They are part of the India Diaspora. From the ancient, remaining record of the frescoes in ruins of India and words passed down from Brahmanism, we can find palmistry was very popular in India at that time. In China, palmistry also has a long history. Since the Zhou Dynasty (1046-24+ BC) which is about three thousand years ago, it has prevailed. The first comparatively complete and systematic palmistry work in China appeared in Western Han Dynasty (202 BC- 9 AD) which was written by Xu Fu.
You should choose a hand. There are different schools of thought on this matter. Some people think the right hand is for females and the left hand is for males. Both hands are important but one is dominant and the other is passive. The left hand usually represents what you were born with physically and materially and the right hand represents what you become after you grow up. So, the right hand is dominant in palm reading and the left hand is the supplement.
