After the establishment of the Zhou Dynasty, the clan royal family and the meritorious yuanxun were divided into various places, and the feudal royal family, which is also known as the sub-feudal system. The Qin Dynasty, which replaced the Zhou Dynasty, was counterintuitive, and the then Chancellor Wang Zhen actually suggested that the First Emperor divide his sons and disciples to go to various places and establish a feudal state. However, the heroic Qin Shi Huang flatly refused, and believed that the sub-feudal system was the main reason for the disintegration of the Zhou Dynasty, so he began to implement the county system. However, the Qin Dynasty died after the second death, and Han Gaozu, who replaced it, believed that the reason why the Qin Dynasty existed for such a short time was because there was no division of sons as kings, which led to the demise of the Qin Dynasty, and no clan stepped forward.
In view of this, Han Gaozu restored the sub-feudal system on the basis of the county system, which was called "county-state parallelism" in the early Han Dynasty, and in order to prevent others from usurping the throne, he also said that "those who are not the king of the Liu clan, the whole world will strike together." However, although Han Gaozu had foresight, he could not imagine that the Seven Kingdoms Rebellion that almost subverted the Han Dynasty during the Reign of the Han Jing Emperor because of the strength of the local princes. After this incident, both the Han Jing Emperor and the Han Wu Emperor focused on cutting the domain, and for a while the sub-feudal system was once again snubbed. Since then, the county system has basically become the political mainstream of the dynasties, but by the time of the Ming Dynasty, it has changed again.
After the founding of the Ming Dynasty, Zhu Yuanzhang, on the one hand, was worried that someone would overthrow the Ming Dynasty, and on the other hand, he was worried that his descendants were plotting to engage in civil war, so he introduced a new sub-feudal system: he sealed several of his sons to dangerous places as kings, and let them serve as military commanders in the border areas to resist foreign enemies, that is, the so-called Kings of Jin, Qin, Yan, and Zhao. However, Zhu Yuanzhang was probably just as Han Gaozu could not imagine the rebellion of the Seven Kingdoms, and Zhu Di, the King of Yan, would raise an army in Beijing in the future and go south to seize the throne of his nephew Zhu Yunjiao. The next thing to talk about is Zhu Yuanzhang's son, but he is much more obedient than Zhu Di, the King of Yan, that is, the tenth son, Zhu Tan, the King of Lu.
Since his title was "King Lu", it is conceivable that Zhu Tan's ruling area was naturally the Shandong area. Born in 1370, he was crowned King of Chu two months later, grew up in the palace as a child, and when he was 15 years old, he went to Yanzhou to take the domain. Zhu Tan had a hobby, he was "a good writer, good at poetry", and believed in Taoism. It is quite interesting that although he was not very old, he sought the elixir of immortality like Qin Shi Huang, and he did not do anything all day, only knowing how to burn incense and chant the sutra and burn the elixir. Moreover, it is quite experimental, and really ate the so-called "elixir", and the result was "bait and stone medicine, poison and hurt the eyes".
The young Zhu Tan died of poison at the age of 19, and although Zhu Yuanzhang was sad about the death of his son, he complained even more about his absurdity, so his nickname was "absurd", so the tomb of King Lu was also called the tomb of King Lu. After the death of King Lu, he was buried in Mencius's hometown of Zoucheng, and his tomb sat on the north and south, built on a mountain, covering an area of more than 13,000 square meters, quite royal. The Shandong Provincial Museum has long been "coveting" the tomb of King Lu, so in the spring of 1970, the excavation was organized, the tomb was more than 20 meters away from the surface, and there was a sealed door wall and a King Kong wall in front of the tomb, and the tomb passage was 20.6 meters. Among them, there are two rooms in front and back, the front room has a ten thousand year lamp, and the back room treasure box has a "Treasure of king Lu" seal.
Before the imperial case, a group of precious wood carved painted figurines was unearthed, with a total of nearly 400. Because the burial chamber is full of water all year round, more than 6,000 burial items are well preserved, which can be described as countless. Among them, there are the Southern Song Dynasty "Heavenly Wind and Sea Waves" piano, woven gold satin dragon robes, etc., the most precious of which is the gold powder "Sunflower Butterfly" fan inscribed by Song Gaozong himself, as well as more than 20 books such as "Notes on the Four Books" and "History of Du Gongbu Poetry". Since 1985, the Zoucheng People's Government has successively restored the cemetery building and opened it to the public.
