There is an earthen well at the main entrance of my purlin building, and there is a tube well beside it, which is no longer used and buried under the house. Do you have any opinions?

Your question belongs to the category of environmental feng shui. There should be no "wells" around buildings, and the special industries of "wells" are also taboo except shops and factories. According to geomantic omen, the well is dominated by yin, and the Yin Qi is heavier, which leads to bad luck, decreased fortune and exposed fortune, which makes people prone to mental illness or accidents, especially in the East. The reason is that the east is Qinglong, which has always been regarded as auspicious and belongs to the birthplace. It is conceivable that there will be consequences here! The factory owner said that the well has been filled, which is a good thing, but rushing to fill the well has not completely solved the fundamental problem, that is, the aftermath problem ... this problem can be called a feng shui master. I suggest you consult a local gentleman to solve it, so as to solve your worries.
