This refers to luck where the energy of ‘Wood (木)’ among the five elements in Saju (Four Pillars of Destiny) acts strongly.
It symbolizes growth, beginnings, vitality, development, and the power to reach upwards, signifying a period where the drive to start and push forward new endeavors strengthens.
When MokWoon is strong, one tends to develop and grow even amidst difficulties due to enhanced drive and willpower.
