After Sima Yan established the Western Jin Dynasty, Sun Wu in the south stood side by side. He wanted to take a series of measures to enrich the country and strengthen the people, accumulate strength, and unify the world when the time was right. Sima Yan regarded respecting Confucianism as the foundation of his country. A national university (Piyong) was built, with 19 doctors (professors) and 3,000 Taipei students recruited. Confucian activities such as country drinking and shooting are held, and Confucius is worshiped throughout the year. Sima Yan also personally set an example and promoted filial piety. He served his father Sima Zhao for three years (Emperor Liu Heng of the Han Dynasty once issued an order to shorten the mourning time and use one day instead of one month). Next, of course, is economic construction. In the past, it was an agricultural society, and there were no large and small industrial enterprises today, so agricultural issues were naturally the primary issue. Sima Yan and other princes, ministers and officials personally cultivated a thousand acres of farmland to show the importance they attached to agriculture. At that time, powerful and wealthy businessmen hoarded goods and drove up prices in bad harvest years. The people suffered greatly, so Sima Yan ordered the establishment of Changping warehouse to buy grain in good years and sell it in bad harvest years to facilitate the people. Promote frugality and practice it personally. Relevant departments requested the establishment of seven temples. The seven temples refer to the temples of the four relatives (the great ancestor, great ancestor, ancestor, and father), the second temple (the father and grandfather of the great ancestor) and the temple of the ancestor. Sima Yan believed that the corvee was too heavy and did not allow it. Instead, they used local materials and changed the Cao Wei family sacrificial temple into the royal sacrificial temple of the Jin Dynasty. Seven sacrificial rituals were finally established: Sima Jun, Sima Liang, Sima Jun, Sima Fang, Sima Yi, Sima Shi and Sima Zhao. An edict was issued to promote frugality, and the palace jewels and jade playthings were taken out, and the princes and ministers were given varying amounts of them according to their rank. Yuefu's extravagant acrobatics, ornate carvings and hunting equipment are prohibited. The green silk reins used to control the ox during the sacrificial ceremony were broken. Because green silk was more valuable, Sima Yan ordered hemp ropes to be used instead. An admonishment officer (an official who bluntly complained about the emperor's faults) was established, and Fu Xuan (217-278) and others were appointed to serve. Fu Xuan had a strong and upright character and could not tolerate the shortcomings of others. Every time he proposed impeachment, after writing the impeachment memorial in the afternoon, he would hold the memorial in his hand, dress neatly, stay up all night, and sit upright, waiting for the day to go to court. As a result, no one among the princes, generals or ministers was afraid of him, and the atmosphere in all government units was changed. At the same time, Sima Yan encouraged all officials to speak up and issued an edict specifically: "From now on, even if the things required by the edict or the things I approve, if implemented will cause inconvenience to the society, do not hide it and report it truthfully. "To create a warm society, the guard troops of the former Eastern Han Dynasty royal family surnamed Liu in Shanyang Kingdom (Jiaozuo City, Henan Province) were abolished, and all restrictions on travel and other aspects were abolished. The Cao Wei State's ban on the royal family was lifted, and the order of Cao Wei State's generals to leave their families in Luoyang as hostages when going on expeditions or garrisoning was revoked. To purify the social atmosphere, it is forbidden to study star energy, prophecy and other techniques, order people to inspect the customs of various places, and cancel those evil sacrificial words. Make laws. When Sima Zhao was in power, he began to formulate legal provisions and ordered Jia Chong, Yang Hu, Du Yu, etc. to refer to the laws of the previous dynasty to revise and improve them. In the first month of the fourth year of Taishi (268), Emperor Wu of the Jin Dynasty, this decree was finally revised, with 620 articles. We call it the "Jin Code". Zhang Fei and Du Yu also commented on the "Jin Code", so it was adopted by the Jin Dynasty. Emperor Wu promulgated and implemented it at the same time, and the annotation has the same legal effect as the "Law of Jin". Because this law was promulgated in the Taishi period, it is also called the "Law of Taishi". "Jin Code" plays a very important role in the history of Chinese legal development, deeply influencing the laws of the Southern and Northern Dynasties and even the Sui and Tang Dynasties. Emperor Wu of the Jin Dynasty, Sima Yan, summoned all civil and military officials to attend the explanation in person, and ordered Zhang Hua to copy down the provisions of the new law on the death penalty, and post them in Cantonese at various post stations and in front of governments at all levels to make it widely known to the people. The prince is the foundation of the country, and the issue of establishing a prince as soon as possible is also placed in front of Sima Yan. In ancient times, when establishing a prince, it was important to establish the eldest son of his wife. Sima Yan's queen is Yang Yan. Yang Yan is from Huayin in Hongnong (now Lingbao, Henan). Her father is Yang Wenzong. Her ancestors were the fourth and third princes in the Eastern Han Dynasty. They were also from a wealthy family. Unfortunately, Yang Yan was very young. At that time, her mother passed away. Her uncle Zhao Jun and her aunt treated her as their own child. Her aunt breastfed her herself and gave her own child to others to feed.
From now on, I will sacrifice my life for the country even when I am alive, and I will make straw ropes when I die ("Zuo Zhuan" records that Wei Ke [k] remarried his father's concubines, and was tied into straw ropes by the girl's father to repay your kindness). ”
