There are many brilliant cultures in the world's four ancient countries, which represent ancient civilizations, they are ancient Babylon, ancient India, ancient Greece and ancient China, but after a long baptism of time, only China has continued in this world for thousands of years without change, and such achievements are actually the result of many factors converging. Take Chinese characters as an example, Chinese characters have been passed down in China, and the country has always formed a system of great unification and inheritance for the eldest son.
In fact, the system of the eldest son is talking about a zen system, which was a polygamous system in ancient times, and the firstborn son referred to here is the first son born to the ancient man and his wife. For the emperor in the imperial palace, the eldest son of the emperor can inherit the throne, which is what we now call the prince. After Dayu ruled the water, he was elected as the leader of the tribe by his own tribe, and after Dayu's later years, he ceded his position as leader to Yi, and then Yi gave up his leadership position to Kai, and this series of Zen concession systems contributed to the beginning of the family world, so that the tribe at that time formed a family concept. This concept gradually spread to the Shang Dynasty, and the emperors of the Shang Dynasty gradually used this method to continue the administration of the Shang Dynasty.
Later, after the Zhou Dynasty, the identity of the eldest son was officially determined, the eldest son could inherit everything from the father, while the other children could only inherit a little of everything from the father, but if other children wanted to compete with the eldest son for power and status or the position of the eldest son, they would be regarded as unfaithful, although this was very unfair to the other children, but in the overall situation, this was the best way to avoid cannibalism among the offspring.
However, not the eldest son is the most talented of all the descendants or the best person to lead the country, and there are many examples in Chinese history of the decline of the eldest son or the failure to implement the primogeniture of the firstborn. For example, Hu Hai of the Qin Dynasty, in fact, Qin Shi Huang's original eldest son was Fu Su, but later by the eunuch Zhao Gao's calculations, Hu Hai became Qin II, and later because Hu Hai was absurd and unscrupulous, Zhao Gao held most of the power of the imperial court, and finally the Qin Dynasty was also buried in the hands of Hu Hai and Zhao Gao. In fact, the system of primogeniture is the most appropriate way, and if we compare the history of the West, we will find that the original Charlemagne Empire was divided by three brothers, and finally the country was divided into three countries and lost its original glory.
