How to explain "left green dragon, right white tiger" in Feng Shui?

This is nothing strange, just a feng shui term. As simple as the chemical name of [water] is [[〔H2O〕]]. But it happened that some charlatans pretended to be mysterious, making "Qinglong" and "White Tiger" mysterious, beyond the understanding of ordinary people. This means that when people don't know that [H2O] is [water], they will feel profound when they hear [H2O], but once they know it, they are nothing.

Four spirits are in charge of spring, summer, autumn and winter. In fact, in addition to the "dragon" and "white tiger", there are four kinds of animals, Suzaku, Xuanwu and * * *, which are collectively called the Four Spirits.

Twenty-eight inns were established in ancient China, which were divided into four groups with seven stars in each group. These four groups are the stars in the sky in spring, summer, autumn and winter. Each season is equipped with an animal and an orientation (see attached figure). Spring matches the East, and its spirit is Qinglong, because Qinglong represents the vitality of spring and the growth of all things. The vitality of Qinglong is equivalent to the germination of flowers and plants in spring. As for summer, the weather is hot, so it is represented by Rise of the Legend. And birds are particularly active in summer, so the spirit of summer is Suzaku. Suzaku is a red firebird. In addition, summer is accompanied by the south. Autumn is full of cold air, and there are more executions in ancient times than in autumn, which is called autumn decision. When autumn comes, yellow leaves fall. So [White Tiger] just represents the loneliness and cold breath of autumn. In addition, autumn is accompanied by the west. Winter is accompanied by the north. Flowers and trees are no longer lush in winter, and animals hibernate, just like collections. Therefore, Xuanwu just represents this season. The so-called [Xuanwu] is a big black turtle, because turtles have a collection image. Black is better for convergence.
