"The sun is the master and the heavenly stems are water": The sun master refers to the life master, which refers to yourself; the heavenly stems refer to the heavenly stems and earthly branches. This sentence means that you are born with "water", and the other four five elements of "metal, wood, fire, and earth" must be balanced around "water".
"The five elements of this life are wood and wood": Water produces wood, so wood is exuberant for water.
"Born in winter": This is easy to understand.
"Must have wood to help you": It shows your strong character. The five elements of the same type, water and metal (metal produces water, and metal is the five elements that produce you), are stronger than the five elements of the different types, wood, fire and earth. In order to maintain the balance of the five elements, we must release the strong and support the weak. If you adopt the method of draining the strong and reinforcing the wood, then the water will produce wood and the water will be deflated. You can also add soil, as soil can overcome water. But you cannot replenish the fire (although replenishing the fire is also one of the ways to relieve the strong and support the weak), because "but avoid too much fire."
From the original meaning of the whole sentence: your name should complement wood and earth.
I understand this literally. It would be best if you could provide horoscopes for detailed analysis.
