According to the ancients, two waters, two soil, one wood, two gold and one fire are better. Jia Mu lives on the moon and lives forever. In the middle of the month, it is wonderful to make water without soil. Running Xijin Nanhuo, Jia Mu is warm but not cold at noon, and good evening. Eight-character water is more important than gold, and it is better to use the name with fire, or the name next to fire, or the name next to wood.
