After Yang Jian established the Sui Dynasty, he felt that the word "Sui" was very unlucky, because the word "Sui" had the word "walk by". Yang Jian believed that this implied that the Sui Dynasty would also leave early. He hoped that his Sui Dynasty could be a long-lasting dynasty, so he got rid of this unlucky one. So the Sui Dynasty became the Sui Dynasty.
The origin of Sui Dynasty originated from Suizhou. Yang Jian's father Yang Zhong was a famous general in the Northern Zhou Dynasty. He fought bloody battles and made many contributions, so he was named "Sui Guo Gong" and ranked 12th. General, later after Yang Zhong's death, Yang Jian inherited the title of his father, Duke Suiguo.
In 581 AD, he destroyed the Northern Zhou Dynasty and established the Sui Dynasty. Before that, the Western Wei Dynasty, Northern Zhou Dynasty, Eastern Wei Dynasty and Northern Qi Dynasty were relatively short-lived dynasties and were destroyed in a short time. Therefore, Yang Jian was also very worried about this. When he saw the word Sui, he felt very unlucky. He felt that if the country was named Sui, it seemed that his dynasty would leave at any time, so He removed the word "Leave" and changed his country's name to "Sui". After Yang Jiantu established the Sui Dynasty, he spent eight years destroying Nanchen and Zuohou to unify the world. "Book of Zhou - Jingdi Ji" records that he followed the Duke Yang Jian to the throne and became king, followed the king Yang Jianjian to have the honorary title, and the emperor was inferior to other palaces. ?
Suizhou was located in Hubei Province at that time. Suizhou's geographical location at that time was quite special. It was located between Xiangyang, an important town on the Han River, and Yingzhou, an important town on the Yangtze River. It was the only way for the Chu State to march into the Central Plains. During the confrontation between the north and the south, the Southern Dynasties often regarded Suizhou as an important defensive stronghold.
In 537 AD, Yang Zhong served Yu Wentai, the Prime Minister of the Western Wei Dynasty. During the Hou Jing Rebellion, Yang Zhong was ordered to seize the Han River Basin. In the Western Wei Dynasty's conquest of the Han River and Mian River Basin, Yang Zhong made great contributions. In order to express his recognition, in 559 AD, Yang Zhong was granted the title of Sui Guogong, with a settlement of 10,000 households, and a settlement of 1,000 households in Jingling County. On the anniversary of the Northern Zhou Dynasty, Yang Jian inherited the title of "Queen Sui" and transferred the fiefdom to another. It expanded to twenty counties and gradually became "Suiguo".
