The five elements of Nayin are based on the year. If your year is "earth in the sand", it can be determined that you are an "earth" person! The five elements of Nayin of the moon, sun, hour and other pillars are very slight and can only be used as a reference. For example, if the five elements in your horoscope are missing wood, which are joy and energy, and the five elements of the moon pillar are "pine and cypress wood", it can be regarded as a small remedy.
