What do numbers and numbers mean in Feng Shui?

Mainly the appearance of the river map. The river map is in the north, belonging to water, so it was born in the sky and 60% in the ground. The south is a fire, Erqi, so it is two fires, and the sky is 70%. The east is a wood, with three trees in the sky and 80% of the land. The west belongs to gold, accounting for 90% of the land, and the middle belongs to soil, accounting for Tianwu, and the land 100%. The river map tells us that two and seven come from the north to produce water, and so on. These ten numbers, the sky represents Yang, which is odd, and the earth represents Yin, which is even. So, one, three, five, seven and nine are days, two, four, six and eight. Ten is the number of positions. One, two, three, four and five are numbers. For the body, six, seven and eight. Ninety is a number for use. Water is first produced in the five elements, and then the other four gases are produced. Heaven produces water, and the earth accounts for 60%, which tells us that the formation of water is divided into two stages. Vaporized water is first formed by the yang in the sky and the moisture in the north, and then formed by the yin in the soil, which becomes the water of the day after tomorrow. The second place made a fire, and the sky was 70%, which told us that the fire was first formed on the ground, and the hot air bred by underground stones rose, and then it was hit by lightning in the sky, forming a fire. By analogy, it is very simple that the birth is the earliest factor that gave birth to the five elements, and the successful number is the achievement of the five elements.
