The eight characters are divided into annual column, moon column, sun column and hour column, so they are also called four columns. Chen Xu's ugliness is not the four treasures of the earth. There is no soil and no root in the eight characters and five elements. This man will be unstable in everything he does. Reason: gold can be taken away by people, fire can be burned out, water can run away, wood can be sawed down, and the only soil can never be cleaned up, so it is a root.
Eight characters without roots can be remedied by name and screen name. Mr. Lu Xun has a text called "The Soil of Young Runners", which has no roots in eight characters, hence the name.
