How to prove the real existence of Xia Dynasty?

Xia Dynasty (about 2000 BC-about 65438 BC+0600 BC) was the first dynasty recorded in China's history books. According to historical records, there are many countries in the Xia Dynasty, so it is generally believed that the Xia Dynasty is a country in the form of tribal alliance (while Chinese mainland's Marxist historiography thinks that the Xia Dynasty is a slave country), and there are a certain number of bronze and jade vessels in the cultural relics of the Xia Dynasty (cultural relics before 1600 BC), so its culture/civilization level is higher than that of the late Neolithic culture. But so far, there is no written evidence of the existence of the Xia Dynasty in archaeology (the earliest written record began in the early Western Zhou Dynasty), so its real existence has not been officially confirmed. However, we can't deny the existence of the Xia Dynasty, because if the words at that time were written on some hard-to-preserve objects, it is entirely possible that they would not be handed down. The existence of Shang Dynasty was also confirmed by the easy preservation of Oracle Bone Inscriptions and bronzes. According to historical records, "there are five stars in jade as many as pearls, and pearls are as bright as pearls." According to comprehensive calculation, there was a good five-star party on February 26th, 65438 BC+0953 BC, which can be used as a reference for dating the Xia Dynasty.

According to historical records, the Xia Dynasty was a country founded by Yu's son Qi. Yu Xia changed from him to the hereditary system of the throne through his son, not the previous abdication system. The Xia Dynasty * * * inherited the kings of 13 and 16 generations (when it comes to the kings of 14 and 17 generations, it is mainly a controversial issue whether Dayu is the monarch or the leader of the tribal alliance), and it was destroyed by the Shang Dynasty about 400 years later. In the Xia Dynasty, agricultural civilization reached a high level. According to legend, Yi Di, the minister of Yu Dynasty, began to make wine, and Shao Kang invented the method of making wine. In order to meet the needs of agricultural production and explore the laws of agricultural time, the lunar calendar, sometimes called the summer calendar, was invented at that time and is still popular in modern times.

Animal husbandry has developed. There are a large number of slaves engaged in animal husbandry, and some clan tribes specializing in animal husbandry. The breeding of horses has received great attention. In addition, the pottery industry may have become an independent and extremely important industry in the Xia Dynasty.

As for bronzes, China has discovered bronze knives of Erlitou culture. If Erlitou culture is regarded as Xia Dynasty culture, then this bronze ware belongs to Xia Dynasty. The tools used by Xia people are mainly stone tools.

There are cars in the capital of Xia Dynasty, but it is impossible to confirm whether it is a rickshaw or a carriage, because the rut is only 1 meter wide, which is different from the rut of Shang Dynasty, which is 2 meters wide. Shang Dynasty has confirmed the use of carriages.

Xia people have mastered a lot of astronomical calendar knowledge, and Xia Zhengxiao is the earliest almanac in China. Copper casting industry is an important emerging handicraft industry in Xia Dynasty.

The appearance of jade ritual vessels in the first and second phases of Erlitou cultural relics shows that it has reached a considerable cultural level.
