What happened in Wuding period of Shang Dynasty? Both large and small sizes are acceptable.

After the brief rule of Pan Geng, Xiao Xin and Xiao Yi, the Shang Dynasty entered the peak of its history-Wuding era (known as "Wuding Zhongxing" in history, but in fact the achievements of this era far exceeded any previous era). Wu Ding, King of Shang Dynasty, reigned for 59 years (this is indeed a miracle in Shang Dynasty with low average life expectancy). When he was young, he was sent by his father, Xiao Yi, to experience life through folk labor, so as to understand the sufferings of the people and the hardships of agriculture. He succeeded to the throne in 1250 BC, but he ignored state affairs for the first three years after he ascended the throne, and "the voice of your majesty is unknown to the world" (there is a saying that the reason for his "silence for three years" is to mourn his father, but this statement is quite unreliable).

BC 1247, it is said that inspired by a dream, Wu Ding found a slave who built a wall among the people and appointed him as the Prime Minister. This man is the famous Fu Shuo in history. With the help of Fu Shuo and Gan Pan, Wu Ding made great efforts to consolidate his rule, strengthen his national strength and enable the Shang Dynasty to rule. In the era of Wuding, a huge bureaucratic system began to take shape, and a relatively fixed and huge army was formed.

After the internal affairs were consolidated, Wuding began a large-scale conquest. First, it forced the surrounding small countries to submit completely, and then attacked the small countries such as Fu, County and Rang in the south of Shanxi and the west of Henan to expand their territory. At this time, the ghost party, Qiang party and Tu party of northwest minorities became stronger and stronger, which became the worry of the Central Plains dynasty and the focus of Wu Ding's foreign war. The war with the ghost party lasted for three years. After years of war, these countries were finally defeated and the threat was lifted. Wu Ding also explored southern Xinjiang and conquered foreigners, Pakistanis and tigers in Jingchu. By the end of Wuding, the Shang Dynasty had become a country with a vast territory and numerous tribes, starting from Gansu in the west, the seashore in the east, the desert in the north and Jianghan in the south, which actually laid the general territory of the Chinese nation before Qin Shihuang.

In order to control the vast conquered areas, Wu Ding enfeoffed wives, sons, heroes and other obedient minority leaders, and the enfeoffment system was called Hou or Bo, which was the first of its kind in the Zhou Dynasty. Among them, the ancestors of Zhou people were conquered in Wu Ding era and accepted the title of Shang.

Ancestor worship, a prominent feature of China culture, has been stereotyped in this era. Superstition about Oracle Bone Inscriptions has also developed to the extreme. In this era, it is popular to sacrifice the living (the main source may be prisoners of war), and there are many records of sacrificing hundreds of people in one sacrificial ceremony.
