Four subjugated kings were buried on a mountain at the same time. What happened?

Because of national subjugation, we are together. The place where these four kings of national subjugation were buried is the historic city of Luoyang. As an ancient historical capital, many dynasties built their capitals here, which is enough to show that it is a treasure trove of geomantic omen. The living build their capital here, and naturally there will be dead people building cemeteries here. ? But it happened that four kings of national subjugation were buried on a mountain, Mangshan Mountain. We are familiar with the four kings of subjugation and Li Yu, and we are not familiar with Meng Changjun, the late ruler of the Southern Dynasties and Shu. Of course, it is no coincidence that they are buried in a mountain, not only because they are all kings of national subjugation, but also because their experiences are basically the same.

Although he is the master of national subjugation, most of them enjoy their old age. Liu Chan, for example, was warmly received by Si Mazhao after his throne was overthrown, and was also named Duke of Anle County. He had a very happy time in Luoyang at the age of 64. Chen Ye is so. After his dynasty was overthrown, he was also named Duke of Great Wall County. In Luoyang, he sang every night and lived a drunken life. At the age of 52, he dragged himself down and died. Although he is the monarch of national subjugation, he is more headstrong than any monarch. As for Meng Changjun, although he was also a successful emperor when he was in office, his evaluation by later generations was quite good. But his biggest shortcoming was that he was still far from being a good minister, and finally he surrendered without much resistance. Later, he was also named King of Qin, but he died the fastest among the four kings of the kingdom, because he died only seven days ago at the age of 47. Needless to say, Li Yu himself, as a poet and painter, is not a piece of material for governing the country. After he became king, he lived a more leisurely life.

They were all in Luoyang before their death, and they all had official titles. They happened to be buried in this place after their death. It's hard to say whether this is providence or not.
