The rule of Taikang, also known as the prosperous time of Taikang, was a period of economic prosperity in the whole country after Sima Yan unified the whole country, by taking a series of measures such as rectifying official management and building water conservancy in the early Western Jin Dynasty. During this period, according to historical records, there was nothing in the world, taxes were general, people lived and worked in peace and contentment, productivity gradually recovered, cars were on the same track, and books were in the same language, which was a rare prosperity after the Three Kingdoms.

It showed the stability and prosperity of the society at that time, but in such a peaceful and peaceful environment, why did ordinary people live so hard? One of the most important reasons is that the Western Jin Dynasty was a big family regime. The western Jin dynasty followed the nine-grade official selection system established by Cao Wei, but it had many disadvantages. It became a tool for the big family to monopolize the political power and formed a hierarchy, which led to the constant opposition between the lower class and the ruling grassroots, and also led to the corruption and greed of the landlord class, which quickly intensified the sharp contradictions in the Western Jin Dynasty. Corruption in the upper class makes people's livelihood more and more difficult. Although Sima Yan, the Emperor of Jin Dynasty, made some achievements in the early stage, he lived a dissolute, hedonistic, luxurious and lustful life in the later stage.

To this end, it was specially ordered to collect beautiful women from the people. This behavior has brought extremely bad influence and demonstration to the aristocratic class. According to statistics, at that time, only the harem concubines and maids in Sima Yan amounted to more than 10,000 yuan, which increased the burden on the state treasury. These expenses made the people's taxes heavier and heavier, which brought a huge burden to the Western Jin Dynasty, which was reunified soon at that time.

The bad personal atmosphere of Emperor Tiandi had a very bad influence on princes and nobles, and the trend of comparison became increasingly popular, among which Shi Chong and Wang Kai were the most famous, which brought a great load to the Western Jin Dynasty with weak national strength at that time. However, all these burdens must be borne by the lower classes, so people's lives are difficult. ?
