"Blessed land is blessed with folk houses" means that not everyone in blessed land has a blessing, but blessed land is blessed with folk houses. And those who have no blessings, living in the blessed land is not good, not only can't get happiness, but also become "evil", which is harmful and useless.
"Blessed people live in a blessed land" means that for a blessed person, the place where he lives will become a blessed land, regardless of whether this place is blessed to others.
If expanded, these two sentences illustrate a core content of China's traditional Feng Shui thought: the geographical environment is closely related to people. There is no feng shui without a specific person. Whether the feng shui of a place is good or not depends on the people who live in this place. In fact, it reflects the main idea of traditional numerology and geomantic omen. Other schools of Feng Shui, such as Bazhai Feng Shui and Kong Xuan Feng Shui, also hold this view.

Feng Shui is a mysterious art with a long history in the Chinese nation. It is also known as Kate art and Qing-nang art, and more academically, it is called Kanyu. Feng Shui is the force of nature and the great magnetic energy of the universe. Wind is vitality and field energy, while water is flowing and changing. Geomantic omen is the art of observing geography on the spot, which was also called geomantic omen theory in ancient times. This is a philosophy that studies the laws of the environment and the universe. Since man is a part of nature, nature is also a part of man, reaching the realm of "harmony between man and nature".
The founder of Feng Shui is Xuan Nv, the Taoist goddess. The relatively perfect knowledge of Feng Shui rose in the Warring States Period. The core idea of Feng Shui is the harmony between man and nature, so as to achieve "harmony between man and nature". Early geomantic omen is mainly about the methods and principles of the location, orientation and construction of palaces, houses, villages and cemeteries, and it is a kind of metaphysics to choose suitable places.
There are two explanations for geomantic omen. One is edema disease, which is mostly caused by cold attack, disharmony of lung and qi, inability to communicate with waterways, and water retention in the body. Secondly, it refers to the natural conditions of residential bases and cemeteries, such as veins, mountains and rivers, etc.
