When was the origin of Feng Shui?

The origin can be traced back to BC, but after the evolution of many dynasties, the heyday was the Song Dynasty, during which many professional Feng Shui schools and knowledge points appeared, and numerology and divination produced from Feng Shui also came into being. Later, the technology was adopted by the emperor and applied to the palace construction, but at that time, two geomantic theories were formed, one was the true geomantic omen in the palace, and the other was the folk false geomantic omen as spiritual pillar and belief. The emperor didn't want folk people to learn the real Feng Shui and be usurped by others, so he ordered the following ministers to draw up fake Feng Shui and spread it among the people. Then it began to spread among the people. Until now, the two factions in the society have their own advantages, but they can only do faith because it has not been recognized by the scientific community.
