At the outlet or entrance of water, if there are naturally formed boulders or hills, it is called water mouth sand. In feng shui, it is believed that if there are animal elephants, it must be an auspicious place for ten thousand years. For example, in the mountains and waters of Guilin, there is an elephant standing at a water outlet, like drinking water, in which there must be a dragon vein hidden in the earth. Taking Taipei as an example, the water outlet is located at Guandu, with eight li on the left. The sand shape of the water outlet is like a lion dancing, lying on the left side, and on the right is Guandu Palace, which looks like a large round ball. Therefore, feng shui experts call it the “Lion Embroidering Ball” Bureau, so Taipei is a great auspicious place. I hope that Taipei citizens will cherish this blessed land and not further damage it, otherwise the next generation will gradually become weak and bear the consequences of the evil deeds of the previous generation.
