Are you particular about the number of potted plants in your home?

As far as I know, it’s a bit particular. For example, odd numbers are yang and even numbers are yin. The crown of the tree is smaller than the mouth of the basin, which is a sign of wealth. Flowers themselves are yin, so they are placed on the balcony. Yin and yang are harmonious and everything grows. But if you place green plants in the north house, the north house itself has no sunlight and is yin. If you place green plants again, the yin energy will be too heavy. How to resolve it? Just use the number of plants.
