What do straight hand lines mean?

The lines are also known as palm lines, palm flexion lines. China from ancient times until today, the palm of the main lines are divided into four major lines, said the line of heaven, said the line of people, said the line of the earth, said the Yuzhu, and will be the sky, the people, the earth three lines together called the "three talent lines". And the palm of the small palm lines within the line is ever-changing, a lot of names. Overseas, the main lines in the palm are divided into five, which are: the life line, the intelligence line (also known as the mind line), the emotional line, the jade pillar line and the sun line. And the secondary line is divided into nine auxiliary lines, called: Mars line, health line, combined line, love line, insurance line, intuition line, travel line, Venus line and Mercury line. Generally speaking, people with straight hand lines are active in their work and are more likely to be successful, but the disadvantage is that they are impatient and prone to make mistakes. If both hands have broken palm lines, it means that although this person's personality is strong, it will be more balanced; however, if only one hand has broken palm lines, it is necessary to be more self-adjusted in the development of personality to avoid too much paranoia, so that it will not have a bad effect.
