Yang Heng traveled to the troubled times of the Later Zhao Dynasty, relied on his prophetic knowledge and wisdom to survive the conflict between Hu and Han, and recovered the identity of the Yang family of Hongnong. He based himself on the border, accumulated wealth through precise trade, and gathered core talents (scribes, warriors, and common people). Predict the outcome of the Battle of Feishui, move resources and talents westward to Guanlong in advance, make friends with powerful men, and quietly form the prototype of the imperial army.
After the unification of the Northern Wei Dynasty, Yang Heng took root in Guanlong and married into Xianbei nobles. He pioneered the reform of the military system in the territory (land granting, strict training, meritocracy), and built a huge "Yang Clan" network: he set up academies to cultivate trusted talents (both civil and military), penetrated the military and political system of the Northern Wei Dynasty; established a business intelligence network; He was deeply involved in the politics of the Northern Wei Dynasty, foreseeing and secretly preparing for the rebellion in the Six Towns.
When the six towns were at war, Yang Ximing helped the Northern Wei Dynasty openly and secretly expanded its strength. When the Northern Wei Dynasty split, it became a key ally of Yuwentai (Western Wei Dynasty/Northern Zhou Dynasty), and its military force and land equalization became the foundation of the country. Yang's talents are spread throughout the government and the public, and the power of the group exceeds the imperial power. In his later years, Yang Heng entrusted his successor with the century-old plan to assist Yang Jian in ascending the throne.
In the post-Yang Heng era, the Yang family was as stable as a rock in the power whirlpool of the Northern Zhou Dynasty, continuing to transport elites and consolidate its foundation. He devoted all his efforts to cultivating his direct descendant Yang Jian (son of Yang Zhong) and helping him accumulate meritorious connections. Emperor Xuan of Zhou died suddenly, and the Yang family used the huge power (political, military, wealth, intelligence) accumulated over the past century to help Yang Jian quickly control the court and suppress the opposition.
On the eve of the establishment of the Sui Dynasty, the Yang Family Ancestral Hall worshiped Yang Heng's relics: "Gaozu, four generations of management have established the cornerstone of the emperor. The prosperous Sui Dynasty will be as you wish." In the morning light, Chang'an City is waiting for the new dynasty.
