If you want to be professional, someone specially wrote the Spring and Autumn Draft, so you can have a look.
According to ancient records, it was historians of various countries who recorded their own history. But actually spread to later generations, only Confucius' Spring and Autumn Annals can be seen, which is equivalent to Lu's records. History books of other countries have been lost. (It is likely that the State of Qin set the fire.)
In addition, there are a lot of materials in the annals of bamboo books unearthed during the excavation of ancient tombs, which can make up for the shortcomings recorded in Spring and Autumn Annals and Historical Records. It's a pity that the Chronicle of Bamboo Books was later lost. . .
A classic example is the tomb of Zeng Houyi excavated in Hubei. Cultural relics are quite famous, but there are few records of Zeng Guo in ancient books. According to the geographical location and funerary objects, it is speculated that Zeng Guo is a country with a country in ancient books. Zeng Guo followed the country, probably because the pronunciation of ancient characters was similar, and the words recorded by historians in other countries were different from those used by others themselves. I got it wrong. It's a name.
