I want to make a rockery in the fish pond in the yard. Is there any feng shui principle in rockery?

The fishpond rockery should be placed in the southeast corner or east of the yard. In the southeast, divination is a tree, which belongs to the Qinglong position with the East. Prosperous and Wenchang, it is beneficial to see water. Suitable for water outlet, but not too high, flat and spacious. Due east, the divination is shocking, belonging to wood. Also known as the position of Qinglong, the quality of the East can affect the family's academic development and wealth. The east side should be slightly higher, which means that Qinglong looks up to make money, but not too high. The east is the sunny side. Too high is sunny. The so-called extremes meet. For example, when the East is depressed, it is lucky to see water, which is called the water of the Green Dragon. However, if there is no water or smelly water and sewage in the depression, it will affect the luck of family members and be detrimental to health and career.
