The clearest indicators of the future are the main lines of the palm, although opinions vary on what they represent. To a Chinese fortune-teller, the Life Line, which arcs downwards from the thumb side of the palm to the wrist, is an indicator of life span. Western palmists, however, think this line is more likely to signify quality of life.
尽管大家对掌纹所代表的含意众说纷纭，但能预测未来最清楚的主要标志是尺寸和掌纹突陷的形状。对中国算命先生来说，手掌从大拇指旁边往下呈弧形延伸到手腕是生命线，指示人的寿命。然而西方的手相师却认为，生命线更可能显示的是生活的质量。
