A thumb reaching the second joint of the index finger signifies strong will, firmness, loyalty, and meticulous consideration before making decisions.
If excessively long past the middle joint of the index finger, it suggests arrogance and a touch of ruthlessness in seizing positions or love for oneself.
On the other hand, a short thumb indicates an unstable temperament prone to change, often pursuing immediate desires regardless of consequences. These individuals are ambitious.
A very short thumb indicates gullibility and susceptibility to deception. However, they are often quick workers.

When divining, if the upper phalanx is short, it indicates wisdom and many desires.
A long upper phalanx signifies straightforwardness and logical reasoning.

When observing the thumb in fortune-telling, if it remains closed and always stays close to the index finger, it often indicates a reserved individual with high discretion, prone to concealing and masking their behaviors, lacking transparency and openness.
A thumb that is flexible and bends backwards suggests a kind-hearted person with empathy, capable of enduring all hardships. However, excessive flexibility may indicate disloyalty.
A gentle thumb signifies a person with many desires, prone to stumbling and readily chasing their desires.
Those with a stiff thumb are often stubborn but very practical, straightforward, and kind-hearted.

To relax your hand, gently shake it and then place it on the table. Look at the distance between your thumb and the other fingers and the palm. If your thumb extends outward at a 90-degree angle, you are very confident in yourself and often make decisions independently.
If your thumb extends outward at a 45-degree angle, you need freedom. You dislike taking responsibility for others.
If your thumb is close to the palm, you enjoy spending time alone, preferring to work independently. You often feel uncomfortable around those who enjoy noise and chaos.
When placing your hand on the table, if your thumb touches the palm or is under the palm, you need more confidence. Expressing your emotions and discussing your issues with your parents, loved ones, and trusted friends is crucial.
The thumb is divided into three segments. If one or two segments are longer than the rest, you will have more energy in those segments. The top segment represents the ego, indicating your creative abilities and work ethic. It also shows your influence on others. The top segment is usually as long as, or longer than, the second segment.
If this segment is long and thick, it indicates that you are stubborn and want to control situations. A sturdy top segment shows a willingness to strive for success.
