Dong'e Ejiao's "time" and "position"

The National Master Guru Nan Huai-yu once said: "Scientific science, philosophy, and personnel are all good things. When you do anything, you must pay attention to two things: time and space, time and space."

It is also a specific time and space that gives special value to artifacts, and also leaves a number of national treasures in the long history of China, such as the nine tribute gums.

In history, the earliest mention of the "Nine Tributary Gum" began in the Northern Wei Dynasty (AD 420), after the Northern and Southern Dynasties, the Tang, the Five Dynasties, the Ten Kingdoms, the Song Dynasty, the Ming Dynasty, the Qing Dynasty, and the Ejiao as a royal tribute. Its history of production reached its peak in 1871 when it was in the Tongzhi era of Qing Dynasty. At that time, the Tongzhi emperor dispatched four imperial ministers to Shandong Dong'a supervisor for the use of donkey-hide gelatin. Because of the refined materials used, the craftsmanship was exquisite, and it was refined after nine days. Made famous.

The great influence of this trend has far-reaching influence. It can be seen from the folk songs circulating around Donga County today. The song sang: "The little black donkey, the white belly, the pink nose powder powder hoof, the three wells by the side of the Arab-Israeli well, the Huangjiafang to roll, the winter solstice slaughter to take its skin, the chewing gum had to use Dong Ashui."

This seemingly ordinary rural minority precisely broke the essence of Ejiao – the secret of Nine Tribute Gum: The selected donkey species must be a black donkey; the black donkey stocking environment must be between the landscape; the refining time must be the winter solstice; Adhesive water must be Dong A groundwater.

The medical techniques in ancient times showed that the water in East Azerbaijan is “clear and heavy, and its sexuality tends to be lower, which is equal to the weight of water next to it.” It is the water from the sun to the shade; It is also the time when a yang is born: When it is cloudy, it is taken to the water of yin, which is the yin to the yin.

The selected donkey skin of the nine tribute gums is also quite particular. It must be “a pure black disease-free ass, taken from the winter solstice,” because before and after the winter solstice, the donkey skin is thick and light, and nutrients are abundant. The finest raw materials. The skin color of the donkey is black, black is the water of the genus, and the donkey belongs to the fire animal, and it is also the typical yin and yang.

Not only this, but even the sang wood fire used in the refining process is very particular about it. Qin Yufeng, a representative inheritor of the intangible cultural heritage of Dong'e donkey-hide gelatin production technique, told reporters: According to Li Shizhen's “Compendium of Materia Medica,” the fire has the points of yin and yang, and only the sangmu with uniform firepower, stable fire, and high temperature. Yang Huo Lianjiao can be combined with water and fire in the east to reach the yin and yang in the east.

Obviously, the water of Dong'a is added to the "black disease-free health asses". It is the yin and yin. It is a geographical advantage, and the winter solstice is the time of year when it is cloudy and it is the time of day. There is also a need for "people and harmony," which is the skill of the inheritors of the past.

It is also the clever movement of the weather, geography, and humans. Perhaps the emperors have perseveringly believed that the small amount of donkey-hide gelatin produced by the water in that place is the top product of nourishing yin. , full of its longevity, health hope.
