1. At the latest in the Song Dynasty, jadeite was introduced to China, but the quantity was very small. After the Ming Dynasty and the early Qing Dynasty, the exchange of jadeite culture between China and Myanmar became more and more frequent, and more jadeite raw stones and products were introduced into China.

2. In the book History of Science and Technology in China, British historian Lee Yue Se believes that jadeite was introduced to China from Myanmar via Yunnan after the 8th century/kloc-0. The study of ancient jade in China shows that there are few jadeite products in ancient jade. Although there are some literature records and a few archaeological discoveries, it is still inconclusive whether it is really Burmese jade.

3. According to the records in ancient books, jadeite began in the Eastern Han Dynasty, but the archaeological community has not excavated the jadeite cultural relics in the Han Dynasty or the Song Dynasty, so the earliest time when jadeite flowed into China needs archaeological research.

4. It was not until the18th century that jadeite really entered Yunnan, China in large quantities with the progress of science and technology.

5. Emerald entered China in the middle and late Qing Dynasty, and Empress Dowager Cixi pushed it to a climax (see the picture of Empress Dowager Cixi wearing an emerald bracelet in Baidu). It has been about 600 years since it entered China, and it is a tribute from the king of Myanmar to the Qing Dynasty.

Xiaobai asked when Jade was introduced to China.

Then the time when jadeite was introduced into China should be before this. According to historical research, during the Yongle period of the Ming Dynasty (about 1403), the society of the Ming Dynasty was stable and the economy was prosperous, and the Ming Dynasty expanded to the surrounding areas. On this basis, vigorously develop Yunnan frontier and Tengyue Sanlitun foothills, so that western Yunnan, especially Tengchong, can be greatly developed.

According to the investigation in Yunnan and Hebei, as early as the Ming Dynasty, Tengchong, Yunnan Province entered Meng Gong, a jade distribution center in Myanmar, to do business. By the end of the Ming Dynasty, the jade industry in Tengchong, Yunnan had reached a certain scale.

Xu Xiake, a native of Jiangyin in the Ming Dynasty, was first recorded in his travel notes. Archaeological findings show that jadeite began to be used in China in the Ming Dynasty, and entered the palace in the Yongzheng period of the Qing Dynasty. The scope of use expanded during the Qianlong period, but by Jiaqing, the price exceeded that of Hetian jade. It can be seen that the jadeite at that time only circulated in a small range.

The cultural origin of jadeite. How did the jade come down?

The name jade was originally the name of a bird. The male is called a bird, and the female is called a kingfisher, hence the name jade. In the Ming Dynasty, Burmese jade was introduced into China, and was called Cui Fei, which gradually evolved into jade. In fact, the value of early jadeite is not high, nor is it valued by the world.

There is another story about the origin of jadeite. In the early Qing Dynasty, jadeite was transported from Myanmar to China through the "Second Silk Road". Hetian jade produced in China at that time was called Emerald. In order to distinguish it, it is called Cui Fei. With the passage of time, Cui Fei has become an emerald.

In Tengchong, Yunnan Province, China, very primitive jades made of jadeite materials have been found many times. For example, in 1987, three pieces of Yufu were unearthed in Longling County, Baoshan District, Yunnan Province, and were identified as jadeite. It is an ancient cultural relic after archaeological inspection.

Jade was introduced into China in the late Ming and early Qing Dynasties, which unified the jade world and influenced overseas with the spread of Chinese culture. From Qianlong to Cixi, emperors of all dynasties loved jade. Therefore, jadeite also has the reputation of royal jade in the Qing Dynasty. The popular view abroad also holds that jadeite is the national stone of China, and it is called "Imperial Jade".

Origin of Emerald: Legend has it that in 12 15, Meng Gong man Yoppa was made into toast. Legend has it that when he crossed the Meng Gong River, he came across a drum-shaped jade on the beach. He was surprised and thought it was a good sign, so he decided to build a city nearby. And named it Meng Gong, which means Drum City.

The third view holds that granite veins and light gabbro veins were formed by metasomatism under the pressure of 12 ~ 14 kPa under the action of hot water solution with high sodium chemical potential.
