Why is history called 420 A.D. called the Song Dynasty and now commonly known as the Song Dynasty is

The Song Dynasty (960 A.D. - 1279 A.D.) was a dynasty in Chinese history that inherited five dynasties and ten kingdoms and the Yuan Dynasty, divided into two historical stages, the Northern Song Dynasty and the Southern Song Dynasty, with 18 emperors and 319 years of Guozuo. The founding emperor of the Song Dynasty was Zhao Kuangyin, so the surname Zhao was the surname of the Song Dynasty, and later generations collectively referred to the Song Dynasty as Zhao Song.

In 420 AD, the Song Dynasty was established by the Southern Song Dynasty (420-479), and in 420 AD, Liu Yu, Emperor Wu of the Song Dynasty, was established to replace the Eastern Jin Dynasty. The country name is Song, and the capital is Jiankang (now Nanjing). It is one of the five dynasties and ten kingdoms.

Because the monarchs of the Song Dynasty were all surnamed Zhao, they were called Zhao Song, which was the same as Li Tang.

The Song Dynasty founded by Liu Yu only existed for 59 years (420 to 479) and had little influence; The Zhao and Song dynasties existed for a long time, with 319 years (960 AD - 1279 AD).

In addition, Zhao Song's political, military, economic, and scientific and technological strength are not comparable to Liu Song, so when everyone mentions Song, they refer to Zhao Kuangyin's Zhao Song, and Liu Yu's Song must be specifically specified as "Liu Song" or "Southern Song Dynasty".

There are many such phenomena, such as the single mention of "Tang", which must refer to Li Yuan's Tang, and if it is the Later Tang and Southern Tang of the Five Dynasties, it must be specifically pointed out.

420 A.D. was the first year of the Southern and Northern Dynasties and the Southern Song Dynasty, because the soldiers of the Southern Song Dynasty at that time were also Song soldiers. And what we usually call the Song soldiers are the Northern Song Dynasty and the Southern Song Dynasty after the Five Dynasties and Ten Kingdoms.

It's to distinguish. Zhao Song refers to the Song Dynasty established by Zhao Kuangyin. Historically, it is known as the Song Dynasty and not only the Zhao and Song dynasties. Such as the Song Dynasty established by Liu Yu in the Southern Dynasty.

The Liu Song Dynasty that was only the Southern Dynasty, generally known as the Song Dynasty, was the Zhao Song Dynasty, because its time and achievements were far stronger than the Liu Song Dynasty, and it was not comparable to it in all aspects.

In fact, there was a Song State in the Warring States Period, which was far before Liu Song.

This Song is not another Song.

In 420 A.D., Liu Yu, the general of the Eastern Jin Dynasty, was the emperor, and the country was called Song, which began for the Southern Dynasty and built the capital Jiankang, known as Liu Song in history. Liu Song was the largest, strongest and longest reigning regime among the four regimes in the south, with four dynasties and eight emperors.

The current Zhao and Song dynasties were established by Zhao Kuangyin (960 AD - 1279 AD) and were the dynasties of the Five Dynasties and Ten Kingdoms and the Yuan Dynasty in Chinese history. Therefore, in order to distinguish between the two, people call them Liu Song and Zhao Song.

Liu Yu (April 363 - June 422), the name Deyu, nicknamed Jinu, was born in March of the first year of Xingning. A native of Jingkou (now Zhenjiang, Jiangsu), he was an outstanding politician, military strategist, and reformer during the Northern and Southern Dynasties, and the founder of the Liu Song Dynasty of the Southern Dynasties.

Liu Yu came from a poor family in his early years, joined the army during the Long'an period of the Eastern Jin Dynasty, rose to prominence in the campaign to suppress Sun En, and later took power in the Eastern Jin Dynasty after quelling the Huanxuan Rebellion in 405. In the following ten years, he personally led a large army to pacify Lu Xun, Liu Yi, Sima Xiuzhi and other separatist forces, and later annexed Western Shu to unify southern China; Externally, he defeated the Southern Yan, Later Qin and other countries, defeated the Northern Wei Dynasty, and recovered the south of the Yellow River and the Guanzhong region, so that the territory of the Southern Dynasties reached its peak. In 420 AD, Liu Yu was proclaimed emperor on behalf of Jin.

During the period of government, in order to be diligent and thrifty, in internal affairs, he strengthened the centralization of power, rectified the rule of officials, implemented the "land break", suppressed the scholars, suppressed the mergers of the powerful and powerful, reused the cold door, pardoned slaves and maids, reduced strict laws and regulations, revitalized education, reduced taxes and servitude, developed production, so that the people could recuperate, laid the "rule of Yuanjia", and also created the political pattern of "the cold people in charge of the secret" in the Southern Dynasties, and was a rare emperor in the history of the Wei, Jin, Southern and Northern Dynasties. He is known as the "First Emperor of the Southern Dynasty".

The year 428 A.D. is the Wuchen year in Chinese history, including the fifth year of Emperor Wen of the Song Dynasty, the fifth year of Yuanjia, the twentieth year of Emperor Wencheng of the Northern Yan Dynasty, the first year of Yonghong at the end of the twilight of the Emperor of the Western Qin Dynasty, and the first year of the Emperor Taiwu of the Northern Wei Dynasty.

At this time, it was in the period of the Northern and Southern Dynasties, and the strongest country in the Southern Dynasties was the Song, that is, the Southern Song Dynasty, which was different from the Song after the Five Dynasties and became the Liu Song.

The Southern Song Dynasty (420-479), the first dynasty of the Southern Dynasties in the era of the Northern and Southern Dynasties of China, is also the longest of the four dynasties of the Southern Dynasties, and is also the dynasty with the largest territory and the most powerful national power. A total of four generations, after nine emperors, enjoy the country for 60 years. Because the monarch's surname is Liu, it is also called Liu Song in order to distinguish it from the Song Dynasty established by Zhao Kuangyin later.

It was the period of the Northern and Southern Dynasties (420 A.D. and 589 A.D.). The year 428 A.D. is the year of Wuchen in Chinese history, including the fifth year of Emperor Wen of the Song Dynasty, the fifth year of Yuanjia, the twentieth year of Emperor Wencheng of the Northern Yan Dynasty, the first year of Yonghong at the end of the twilight of the Western Qin Dynasty, and the first year of the Taiwu Emperor of the Northern Wei Dynasty.

It only existed for 59 years, as follows.

The Southern Song Dynasty (420 refers to 479), the first dynasty of the Southern and Northern Dynasties in China, and the largest dynasty in the territory of the Southern Dynasties. In 420 AD, Emperor Wu of the Song Dynasty Liu Yu replaced the Eastern Jin Dynasty regime, changed the name of the country to Song, and set the capital of Jiankang (now Nanjing). Because the Guoming file is surnamed Liu, it is also called Liu Song in order to distinguish it from the Song Dynasty established by Zhao Kuangyin later.

Answer C: This question aims to test the knowledge point of "the establishment of the Northern Song Dynasty". According to the analysis, in 960, Zhao Kuangyin, a general of the Later Zhou Dynasty, staged a mutiny in Chenqiaoyi, and his soldiers put a yellow robe on him, and Zheng Zheng shouted "Long live". He established the historical Northern Song Dynasty.

The Three Kingdoms, the Two Jin Dynasties, the Northern and Southern Dynasties, the Five Dynasties and the Ten Kingdoms, were more chaotic at this time.
