手相, or palmistry, is the practice of interpreting the lines and features of a person's hands to gain insights into their personality and future. Practitioners analyze various aspects, such as the length and shape of fingers, the lines on the palm, and the mounts at the base of the fingers. Each element is believed to represent different traits and life experiences. The main lines examined in 手相 include the heart line, head line, and life line. The heart line relates to emotions and relationships, the head line reflects intellect and decision-making, and the life line indicates vitality and life changes. Many cultures, including 中国 and 印度, have their own traditions and interpretations of palmistry.
