The ancient geomantic omen created the immortal and lifelike tomb for thousands of years, which is a good proof! As for some other wonderful uses of Feng Shui, we can't deny its scientific nature just because modern science has not proved it! Just like Chinese medicine in China, during the period after the founding of New China after liberation, many people in China believed in western medicine, denied the value of Chinese medicine, and said that Chinese medicine was unscientific and was cured by touching a few Chinese herbal medicines, which was simply nonsense.
But now it is not only proved that Chinese medicine is scientific, but also many foreigners study Chinese medicine!
So what modern science can't prove doesn't mean superstition! However, it is undeniable that some almost absurd contents have been added to Feng Shui by later generations. We can't deny the scientific nature of Feng Shui just because of these superstitious contents!
