Mercury Mound is located below the little finger, mainly reflecting a person's talent, emotions and expression ability, which shows the specific and subtle aspects of a person.

　　1. Mercury Mound is particularly low and indented, showing a strong connection with Mars

　　They lack confidence in handling matters on their own, are unable to face harsh and complex reality, and prefer to invest or partner with others rather than run a business independently. They are extremely in need of security. They have a poor memory and tend to forget what they just did immediately, which means their mind is not very flexible and their reaction is slow. At the same time, they are quiet and not good at socializing, so naturally their speaking ability is poor. These people lack decisiveness in doing things, have no leadership skills, and no business sense, especially when the Intellect Line has defects, this becomes more obvious. Because these people often miss good opportunities, they find it difficult to succeed in their careers, have bad luck, and live in poverty.

　　2. People with appropriately full Mercury Mound

　　They have talent and ability, are good at writing or eloquence, can express their thoughts and emotions appropriately, and are often moved by others' talents, thus being recognized and valued, and starting their own business. They are smart and quick-witted, have very outstanding commercial skills, and most of them achieve success in business. As a result, they have more material wealth.

　　3. People with overly full Mercury Mound

　　They are especially able to display their knowledge, but often exaggerate and overstate. These people usually have talent but use it in improper ways, enjoy playing small tricks. They are sharp, but because they like to challenge without considering the means, or are willing to do anything for profit. They are also usually eloquent and deceitful, and once they exceed this limit, they are likely to fail. A woman with a full Mercury Mound is generally popular with the opposite sex. Water represents romantic relationships, emotions and popularity. Just like those with a favorable Ba Zi (Eight Characters), people with a strong water element usually have a richer emotional life than ordinary people.

　　4. People with flat Mercury Mound

　　Although they don't have special talents or are not good at communication, they live a realistic life. Most of them are civil servants or laborers, belonging to people who live realistically.

　　5. There are marks on the Mercury Mound

　　If there is a Star Pattern on the Mercury Mound, it indicates that this person is very stubborn and resistant to advice, leading to failure due to not listening to others' opinions. If a Cross Pattern appears, it indicates that this person has bad habits, such as stealing or other behaviors. If someone has a cross pattern, one should pay attention to their daily lifestyle and cultivate good qualities and moral cultivation. If there are spots or square patterns on the Mercury Mound, it means that this person is prone to failure in the business world, encounters setbacks, or has signs of bankruptcy.
