What does feng shui mean?

In geomantic omen, the key point of choosing a day for Yin and Yang houses is to help the dragon and the direction. You need to use the user's eight characters and five elements to select the date. Generally speaking, Wang lung in Yangzhai doesn't need help, but mainly helps. Yin house should give priority to the undertaker's birthday attribute and choose the auxiliary dragon attribute. Worship for happiness is the eight-character attribute of the collision between the date selection and the burial master.
