From the theory of geomantic numerology, renaming can affect and change a person's fate. We regard the individual as Yang, so the name of the individual is Yin. Yin and Yang are closely related and inseparable, and they also influence and interact with each other. Therefore, people and names are inseparable, and people can't live without "names". The ancients did not have "name" and "share", that is, their status was low. Moreover, the balance between yin and yang is complementary; If yin and yang are out of balance, there will be a vicious circle. In other words, people not only can't be anonymous, but also need a good name that matches them and suits their needs. On the other hand, it shows that changing the name can affect and change the fate to a certain extent.
In real life, whether a person's personality or fortune will be obvious because of the change of name. Mainly depends on this person's living environment and contact things. Not only that, many people change their names when they are young, and their five words may have a greater impact on themselves. If you change your name and surname when you are old, the impact on people's fate is almost negligible.
