How long does it take to learn Feng Shui-I can't find a good place without a job, and I have been vain in my articles all my life. If predestined friends, those who have learned something in their twenties, those who have been bred by geomantic omen in their forties, will start to emerge, and those who have been bred by geomantic omen in their sixties will become famous. Since then, Feng Shui masters have become famous all over the world. Just like a famous teacher, he can meet one or two good students in his life, which can be called educating everyone.
