If we look at the history form the end of the Han dynasty up to and including

During the Tang dynasty there was an extension of the boundaries with China spreading its control out to Siberia and North Korea and the country now known as Vietnam (Anonymous, 2000, Hall, 2000). The control of the silk corridor was even extended into the area known today as Afghanistan (Anonymous, 2000).

This time was followed by the Jin dynasty. This lasted from 265-420 and was seen to bring the country back to unity for a short while. However, the time was not peaceful. There were many conflicts with external forces, such as the nomadic peoples at the boarders. Although there was dissary, there were also several achievements from Medical doctors. Ge Hong was an alchemist and doctor of the Eastern Jin Dynasty (317-420). His work Mawangdui, Changsha, Hunan, The Book of Master Baopu summarizes China's ancient alchemy and records many observations of chemical phenomena, making it an important book for the study of the history of chemistry in China. Ge was the first doctor to write about smallpox. Although it was around the year 1000 that doctors in China discovered how to prevent smallpox by the inoculation method, they did not publicize it until 1500, and Western scientists did not realize that vaccination could prevent smallpox until the early 19th century. Secondly he discovered ‘the most important formulary of the Jin Dynasty. “Entitled Emergency Formulas to Keep up One’s Sleeve” (Bei ji szhou hou fang, this book featured the use of simple and inexpensive, yet effective formulas’. (D.Benksy & R. Barolet). He would use seaweek to treat goiters, sheep liver to treat blindness etc.

There was a conflict with Korea in the beginning of the seventh century, this weakened an already unpopular dynasty and the power was lost due to public rebellion, assassination and disloyalty (Anonymous, 2000).

The country was finally reunified under a short lived, but notable dynasty. The Sui dynasty started its' reign in 589 and lasted until 619 (Eichman, 2000. Hall, 2000). During this period, China was re-centralized, and again its medicines continued to develop. The rule was string, many competitors have noted that although there many political achievement in creating and maintaining a unified country, the dynasty was also harsh. The reason for the success of this was due to the fact that the dynasty was part barbarian having Mongol blood in the line rather than descending from the Han Chinese and had strong power bases in the north. This dynasty is often compared to the ruthless Qin dynasty (Hall, 2000).The dynasty did not last long, and it is thought that the early demise was due to the way in which the tyrannical regimen made demands on the population. The Sui Dynasty imposed very high taxes ion the people as well as sung compulsory labour (Hall, 2000). The result of this was the improvement of the infrastructure of the country, for example the building of the Grand Canal, a project seen as a great engineering feat and the reconstruction of the Great Wall of China (Anonymous, 2000).
