What is a sinkhole in Feng Shui?

A sinkhole is a sinkhole. It's too old. Commonly known as the evil of heaven and earth, it is the evil of crape myrtle. Generally speaking, this day appears in the first three days of the lunar calendar, such as 7, 15, 28. If you just want to avoid the sinkhole, don't move for three days. In the end, it's the old saying (don't be superstitious).
