If a person's little finger is often separated, he is certainly not good at socializing and is also not skilled in writing.

Those who separate their thumb when extending their hand appear to be steady on the outside, but are often conceited and show a stubborn will and a positive attitude. They have their own opinions or are confident. According to palmistry, such people have a rational side, but sometimes they can be unreasonable and lack the grace of cooperation with others.

Those who open their ring finger when extending their hand are kind and amiable towards others, but are stubborn and unkind towards their own family members, lacking the empathy to understand others, thus easily causing family disharmony and disputes.

Those who open their little finger when extending their hand are mostly poor at speaking and writing, completely ignorant of art, and indifferent to science. In severe cases, this may even affect the fate of their children.

Those who open their index finger when extending their hand display an independent posture, without any dependency, but lack the broad-mindedness to coordinate with others.

These people lack team spirit and cannot work together with others to run a business.

Those who keep all five fingers together when extending their hand are always careful, meticulous, and cautious, never wanting to make mistakes.

Those who extend their hand with all five fingers spread out have a cheerful personality, are kind-hearted, talented, gentle, optimistic, and easygoing. However, they may have weaknesses such as weak willpower, fear of trouble, inability to keep secrets, and a tendency to exaggerate.

Therefore, they have better luck in terms of wealth.
