In the history of Feng Shui development in Qing Dynasty, when did it spread to what country?

The geomantic omen of Qing dynasty has entered the place where arowana and fish live together. However, in the early years of Kangxi, Yang Gong Feng Shui led by Jiang Dahong was righted by the book "Distinguishing the Meaning of Geography" and was later called "Sanyuan Feng Shui". However, after the death of Jiang Gong, there were more than 100 schools, but none of them were authentic. There are many books to research various schools at that time. In modern times, the real spread of "exploring Feng Shui" began in the Tang Dynasty. A group of famous astronomers in the Tang Dynasty followed the footsteps of Jian Zhen's eastward journey and spread to Japan. They were worried that Dongyi would bring disaster to China, so they founded a pseudo-geomantic omen, which later spread back and opened the Warring States period in the field of geomantic omen. It still hasn't subsided. Because true geomantic omen affects a country down to personal safety, the true master rarely dies a natural death since ancient times, so it is stipulated that it should not be spread arbitrarily, especially if it brings disaster to the country and people, the heirs must abide by the precepts.
