What are the stresses on the installation of photo wall in geomantic omen? Do pictures need to be selected according to their own numerology?

Not necessarily. Since you are a big sea water, do you need to add more water? In China's traditional culture, both the Book of Changes and Feng Shui culture emphasize the balance of Yin and Yang, harmony and moderation. Too much water will hurt your soul, and too much water will hurt your loved ones. It is suggested that harmonious guidance should be adopted and green plants should be properly placed on or next to the green wall. Only when they are tall can they breed each other and create a good atmosphere. Good luck.
