In this theory, fire and wood belong to the same element, and both of them have the characteristics of germinating, expanding and upward. Therefore, loving fire and using wood can be considered as strengthening this motivation and helping to maintain health and balance. Water and gold are regarded as the opposite elements of fire and wood. Water has the characteristics of cold, shrinking and falling, while gold has the characteristics of convergence, coolness and convergence. If the water or gold in the five elements is too strong, it will restrain fire and wood and destroy the balance and health of the body.
Therefore, according to this theory, if a person feels that the strength of fire and wood in his five elements is weak, then he can adjust the balance of the five elements by strengthening the strength of fire and wood, thus improving his health. However, how to adjust the balance of the five elements and how to judge the individual's five elements attributes needs to be comprehensively analyzed and judged according to the individual's specific situation, and cannot be simply understood literally.
Therefore, I suggest you seek the help of professional Chinese medicine practitioners or Yijing masters for personalized analysis and guidance.
