In the long history, with the fate of the upper, middle and lower Yuan Jiazi and the constant changes in time and space, the role of Feng Shui will also change. Moreover, the changes of natural mountains and rivers (such as the diversion and depletion of rivers) and the changes of the imperial capital will all cause changes in Feng Shui. Therefore, "feng shui turns around" is not so much that feng shui is out of date, but that current events and the natural environment have changed, and the surrounding environment is different, and the results are of course different. "Turn" means change. Even if the original house has not changed much, the surrounding environment (time, social environment, natural environment) is also very different. This is the mystery and charm of learning Feng Shui. Understand this truth, many problems of Feng Shui can be answered. Only good feng shui will have a good rotation, so we should use our own eyes to discover and cultivate good feng shui treasures, create a better natural and harmonious living environment, and benefit mankind and the whole society.
