Humans have paid attention to agarwood for more than 3,000 years, and it has a history of more than 2,000 years in China. China first appeared in the Liang Dynasty (502-566 AD) in Tao Hongjing's "A Bie Lu of Famous Doctors" and was listed as "Top Grade". There are abundant records of agarwood in the historical materials of Sui and Tang Dynasties, which were further popularized and developed in the late Tang and Five Dynasties. In the Song Dynasty, a good agarwood was known as the "king of incense", the incense culture reached its peak, and "incense" had been completely integrated into social life. Since then, this kind of incense has been used for a long time until the Ming and Qing Dynasties. In the Ming dynasty, it became "an inch of land and gold." However, since the end of the Qing Dynasty, incense culture has gradually moved away from people's lives, and agarwood has gradually been forgotten in the corner of history. In China, agarwood is also used as various decorations as a symbol of status and wealth. According to legend, after losing Jingzhou, he was captured and killed by General Wu. Sun Quan gave Guan Yu's head to Cao Cao for fear of retaliation from Liu Bei and Zhuge Liang. Cao Cao knew his plan and respected Guan Yu's loyalty. He ordered that Guan Yu's body be carved with thyme, and the south of Luoyang where Guan Yu was located was buried with his head as a vassal's gift. In foreign countries, traditional Indian medicine in the eighth century has recorded that agarwood is used as medicine, while the Old Testament records that agarwood is refined into perfume. Aquilaria sinensis appeared on the international trade stage in 13 century, and India was one of the first countries to export Aquilaria sinensis. Aquilaria sinensis and incense road Human beings live in infinite smells. After perceptual and rational choices, they know how to use the spices around them, and gradually evolved into a part of sentiment education-fragrant road. This is a kind of life aesthetics produced by human beings from the enjoyment of olfactory function to the pursuit of spiritual cultivation. Aquilaria sinensis plays an important role in this aesthetic. To put it simply, the definition of incense is "the art of incense", that is, combining the fragrance and smoke form produced by spices with artistic incense props, the arrangement of incense living environment, elegant and beautiful methods of lighting incense and smelling incense, and creating relevant literature, philosophy and artistic works through the above memories or associations, thus making people's lives more interesting. In Shangshu, we have already talked about "the spiritual aspect of incense", and the so-called "the ultimate treatment of incense is the feeling of immortals." He also said, "Xiaomi is not fragrant, but virtue is fragrant." It can be seen that the ancient people's interpretation of aroma is not only material and function. Xiang culture is the most important and special part of China's traditional cultural system, and it is an indispensable blood gene of Chinese civilization. China Xiang culture is a kind of nourishing and health-preserving culture. In China, Xiang culture began in ancient times, sprouted in the pre-Qin period, first appeared in the Qin and Han dynasties, grew up in the Six Dynasties, matured in the Sui and Tang Dynasties, flourished in the Song and Yuan Dynasties, and spread in the Ming and Qing Dynasties. Since the late Qing Dynasty, due to social unrest and poverty in China, the incense culture has gradually faded out of people's sight. Nowadays, people from all walks of life pay more and more attention to traditional culture, and incense culture urgently returns to people's lives. (This article comes from Tianjin Daily) Qin 'an agarwood was made earlier by Yang Fu in the Eastern Han Dynasty. The book contains: "Honey fragrance, if you want to take it first, cut off its roots. Over the years, the skin rots and the center and nodes become black, but they will sink into the water. Is it agarwood? " The Natural History compiled by Zhang Hua in the Western Jin Dynasty is a wonderful book, which records the anecdotes, anecdotes, immortal magic and so on. The record of incense is very interesting. Qinan Township accounts for Qinan City and Yamanouchi. The chief forbade people to take it. Offenders who break their hands are precious, and ebony incense pays. . "Xing Cha Sheng Lan" Panduranga also produces Qin Anxiang. It turns out that "ditto" has all kinds of spices in the south, going out to sea and going up the mountain. The guest who covered the wood exposed the fragrant branches, and the person who died and survived was warm, so he was dug by a big ant, and the ant ate honey and returned, but stayed in the fragrance. After a long time, they are gradually soaked, and the wood is hardened and wetted by the fragrance of honey, and the fragrance becomes better. Its fragrance is immortal, and honey is not old, which means that it is born, and it is also on it; Wood is dead, and honey gas condenses on dead roots, making it moist, which is called sugar knot, which is also the second; The tiger skin is tied with gold thread, and the years are shallow, and the wood honey has not yet melted; There is more woody, less fragrant, so it is the lower ear. Do you have a tape? The rate is more than enough, quite natural. Very few are pure. Huayi continues the exam.

Interpretation: There are many kinds of agarwood in Qin 'an, which are produced in the mountains of the sea (now the South China Sea of Vietnam). For those exposed in the shape of branches of Shen Xiang, the wind tree itself is dead and the tree body is still standing. The air is generally mild, and it is easy to nest for tree ants. Tree ants come back to eat nectar, but the nectar is stained with incense. The original Qin Anxiang and Dezhenxiang are all black wood, which is produced by Qin Anxiang and the price is much higher than that of Zhanchengguo. The same as the original "Qi Nan Xiang", which was unknown in ancient times, was introduced to China, so there are different names for Alignment Nan, Lan Qi, Jia Nan, Qi Nan and Qi Nan, but they are not used. Its fragrance types are green knot, sugar knot, honey knot, raw knot, gold knot and tiger skin knot. It is roughly black and green, and you can draw oil with your fingers. Flexible people are the most admirable. They can lift your breath and keep you from drowning. A real person is twice as good as Huang Jingui, but he will never get it. If you put a little on it, it will smell fragrant as soon as you get to your seat, and it will still linger after you leave. Everything in this world is produced outside the mountain forbidden by the chief. For example, the Duan Xi Institute in Guangdong, which is used all over the world, is an ordinary and valuable stone. However, it must be under the pit, under the rock. As Su Wenzhong said, if a thousand people carry a purse and a hundred people carry a kilo, that is the real Duan Xi and the treasure.

The original text is strange and strange. If it is really strange and blue, be careful to protect it; If used as a fan pendant, rosary, etc. Don't go out when it is too dry or wet, and hide for a few days to prevent the fragrance from being consumed. Tibetan method: use an iron box containing radix aucklandiae as the last box, and put another box outside, with less honey, so as to raise honey at the end and fragrance at the end. When the incense box is round, the honey box is fragrant, the incense box does not need to be covered, and the honey box is covered; In short, Sid, Yinxiang is samadhi. When Qinan sees water, the fragrance disappears, but steaming with hot water is a big mistake.
