Yang Junsong was born in the eighth year of Tang Taihe (AD 834) and died in the third year of Tang Tianyou (AD 906). In Ci Hai, Yang said: Yang is a native of Douzhou (now Xinyi County, Guangdong Province), whose name is Mao Shu and he is good at Feng Shui. Nuozongchao, director of GV, is an official of Dr. Jin Guangguang. Huang Chao made a mistake, broke the Kunlun Mountain, and later went to the world by geography, calling himself "Mr. Save the Poor". "Jiangxi Tongzhi" contains: Huang Chao broke the capital, Yang Junsong broke the economy, the dragon crossed the dry state, and walked in the world by geography, saying that Mr. Wang helped the poor. Died of piety and was buried in medicine. There are records about Yang Junsong in True Geography and Sikuquanshu by Qing Qianlong.
At first, he was just a small official in the palace. He took advantage of the chaos in the late Tang Dynasty to take out the official geomantic literature and spread it around, taking Jiangxi as the center, making Jiangxi the base of geomantic art, and Yang himself became a master of geography. Historically, since the Tang and Song Dynasties, there have been two main schools of geomantic omen in the south of the Yangtze River: Jiangxi and Fujian. Jiangxi took Yang Yi (Yang Junsong) in the Tang Dynasty as the founder, and his theory was based on the mountain situation, also known as the situation school. Fujian spread to the Song Dynasty, but it is still popular in the world. Its theory is mainly based on the principle of regulating qi in ancestral temples, also known as the school of ancestral temples. In this regard, the General Catalogue of Sikuquanshu pointed out: "There are two schools of thought who are good at this. One-day ancestral temple method began in central Fujian, Shanyin, which is not wrong. It is purely based on gossip and five stars to determine the principle of health and grams. It's from Zhejiang Middle School, but the users are very fresh. It is said that Jiangxi's method originated from Jiangxi Renyun, Zeng Wendi and Xie Ziyi, and their research is particularly outstanding. They said that the main thing is the situation, that is, what to play, what to stop, and what to guide. Specifically, it refers to the combination of dragons, caves, sand and water. Everyone else insisted and followed today's Great Jiangnan. " There are also some works that the various schools of Feng Shui gradually disappeared under the rise of Jiangxi School, indicating that Jiangxi Feng Shui School was popular at that time.
Yang Junsong has many works on Feng Shui. He is the author of Han Shu Long Jing, Yi Long Jing, Du Jing, Qing Nangao Yu, Twelve Funeral Methods, Jing, Original Funeral Map, Li Zufu, Black Capsule Jing and so on. , all recorded by Kanyu. Among them, Hanlong Jing is devoted to the situation of mountain dragons; The first part of the Book of Suspected Dragons is about finding branches in the middle, the middle part is about finding dragons in the end and looking back to back, and the next part is about the situation of nodes. The inverted stick burial method is dedicated to acupoints, and there are many sayings such as leaning, covering, bumping and sticking. People who advocate the principle of qi in Feng Shui all push Xu Yangjun's theory. There was a physiognomy teacher named Zeng Wendi in the Back Beam of the Five Dynasties. He was a native and good at geography. He claimed to be a disciple, and wrote books such as Zeng Shui Long Jing and Qing Nang Preface, and passed this skill on to future generations. Liao Jinjing is also a master of Feng Shui, and he inherited Yang Junsong's knowledge. After the Tang Dynasty, many geomantic writers quoted Yang Junsong's geomantic theory. Even in the Qing Dynasty, some scholars wrote books about geomantic omen, such as Sun Guangyi, who wrote The Book of Books.
In the early years of the Ming Dynasty (AD 880), the Huang Chao Uprising Army in Tang Xizong entered Chang 'an. It is said that Yang Junsong took advantage of the chaos to steal the secret art of the Forbidden Jade Letter and fled. He and his friend Pu went south from Ganzhou to Wuchang, Hubei, and met Liao Luan, the Ezhou secretariat who led him to Ganzhou at that time.
