Accuracy is relative and the actual situation is also very important. There are many factors that affect fate. Wu Huaiyun's book contains four aspects: time, space, matter and energy. In other words, eight-character numerology is only calculated according to time. Other factors include the influence of geographical environment, spatial location and environment. In addition to material conditions, there are also people's mental state, which can affect people's future. Therefore, it is best to provide some information about the acquired environment, so that people who measure eight characters can analyze what they want according to the situation.
For example, why do twins have different fates, and the difference between the eight characters is very small, but the environment after tomorrow cannot be exactly the same. Even in the same school, friends and teachers around are in different spatial environments.
Feng shui is to grasp the space, and the eight characters are to grasp the time. What you can try to change is your living environment and your inner way of thinking. Fate can still be changed to a certain extent, and the above can be used comprehensively.
