How many Feng Shui dragon veins are there in China?

A lot. You can look directly at the geographical map. You'll be looking directly at the mountains. This is also correct, but it must be combined with the trend of water. The mountains are the backbone and the water is the blood vessels.

There are also many words such as left green dragon and right white tiger.

After reading many books, my personal understanding is that ancient dragons may be dinosaurs or the like. But the real dragon that our country called in ancient times should be the power of heaven and earth. The soil and water support the people, you can understand this, right?

Of course, a good place can cultivate people with higher quality and more caring people. Then it's normal for this place to be prosperous.
