In this study, the ancient Feng Shui, the Feng Shui customs of the ages and the native Feng Shui were studied in order to secure the objectivity of the Korean Feng Shui and Feng Shui. In addition, geomagnetism was analyzed for important factors and places of Feng Shui in order to supplement the objectivity of Feng Shui. In ancient times, psychology for tribal protection naturally played an important role in site selection, which would have led to Feng Shui logic. Ancient beliefs and natural habits have been incorporated into Feng Shui and developed into indigenous Feng Shui. The Haman-MariSan tomb group is the result of ancient faith and mountain worship, and was a grave that positively used stars worship. 『Hwandangogi』was indicates the generation of positive energy-Feng Shui. The Three Kingdoms era means the development of positive-Feng Shui. From the Unified Silla to the Goryeo Dynasty, Feng Shui was actively used in the political, social, ideological, faith, and economic fields. Feng Shui is the word that reduces the Jangfengdeukshui(藏風得水). It appears in the Feng Shui scriptures of the Cheongoh scriptures and the Guemnang scriptures. Feng Shui means the natural view and the mountain was the mother's body. It means to control the wind that blows and to get water. The negative-Feng Shui is implicited belief in bliss and the positive-Feng Shui makes the space in which the person resides advantageous. As the Confucian culture was established in the 17th century, the inheritance and memorial service of the superiority of the eldest son to the people were generalized. The story of Feng Shui in the clan's was also applied to establishing a culture focused on the firstborn. Especially in the late Joseon Dynasty, Feng Shui influenced Confucianism and filial piety ideology in the people. For the filial piety, the people committed sneak bury(偸 葬), surreptitiously bury(暗葬), coercion bury(勒葬) and grave robbery(盜掘). Later Chosun dynasty pragmatic scholars thought that the creation of human mind is influenced by the natural environment, and therefore applied Feng Shui logic when choosing a place. Feng Shui in China is flat in topography and emphasizes water and constellation naturally. Four-God-Hill(四神砂) plays an important role because the Korean terrain in which the physical aspect of a mountain develops must confine the wind to obtain the water's energy. Applying the contents of the Feng Shui scriptures to the physical aspect of a mountain in Korea, "The Feng Shui Law is the first to confine the wind, and the next thing to get water, this matches the content of the first volume in 『Guemnang scriptures』, on the other hand, the contents of the last volume should be reconsidered as "Feng Shui Law is the first acquisition of water, and the next one is confine the wind." The story of Feng Shui recorded in the Chosun dynasty annals mostly emphasized the shape of the mountain as the first priority. The Feng Shui of the shape theory(形局論) advantage of this mountain also had a great influence on the noble Countryman of the province. The cemetery of the specific fat clan suggested in this study corresponds to the letter type in Feng Shui theory. 'Ya(也)' in 'Ya-kok mountain' is mainly used at the end of the sentence, and interprets it as meaning that in Feng Shui it produces a great sentence. Through the case examples, it is possible to confirm the cemetery customs that emphasize the eldest son by reflecting Confucian thought. As a result of analysis of characteristics of Feng Shui place and geomagnetism, the average geomagnetism of good places is 489.4mG and the deviation is 20.7mG. The average geomagnetism in bad places is 485.0mG and the deviation is 94.8mG. The geomagnetism of a good place is in the range of 490.0mG ± 5 and the deviation is small, a bad place is out of range of a good place or has a high deviation. On the other hand, in the case of the back, front, and ridges of the mountain, which are important in Feng Shui, the deviation of the front and ridges is small in the geomagnetism but the deviation is high in the rear. As a result of studying the distribution of geomagnetism about the components of good place in Feng Shui, a secret understanding In the incoming part, the geomagnetism is high and the left and right sideways are elliptical. The geomagnetism around the key point is very stable and the front has somewhat higher geomagnetism as interpreted by Feng Shui. In order to verify the effectiveness of the geomagnetic measurement, the results of geomagnetic measurements on good places and bad places on Feng Shui, the distribution of geomagnetism in a good place is small in variation, while the geomagnetism in a bad place is highly volatility. Therefore, it is considered that geomagnetism measurement is effective as an objective data supplementing the Feng Shui view of subjective logic. The principle of feng shui should be understood as the natural truths that have been passed down from ancient times. In other words, Feng Shui has been intrinsic to the natural environment and people-centered intuition, and has continued to this day. Therefore, I think that the focus theory of the Korean Feng Shui is the shape theory which takes advantage of various topography. On the other hand, modern Feng Shui should complement the logic of Feng Shui through objective data such as objectification, quantification, and statistics using natural sciencetic methods rather than abstract logic.
