When is the last day of this month, when is the well filled?

According to the theory of geomantic omen, auspicious days should also be chosen for digging wells, and the best time is/kloc-0 from winter solstice to June 22nd from summer solstice. This period is called Yangdun period, that is, Yangqi period, with strong atmosphere and clear water quality. However, it is necessary to avoid the days from the lunar calendar 1 month 18 to February 3, April 17 to May 4. Don't dig wells from summer solstice to winter solstice, especially in July, August and September of the lunar calendar. There is a big tree by the well, which is beyond recognition. Because branches and leaves will cover the water surface, dead leaves will fall into the water, and insects will also fall into the well, polluting the water quality, making the water dirty and affecting the health of users. Once the well is dug, it can be used for generations, so if the water quality of the well is not good, it will affect many generations. In addition, the well near the stove is also very embarrassing. According to feng shui theory, fire and water collide, which will bring bad luck. From the perspective of life, the black smoke from the stove will pollute the well water.
