After the death of King You of Zhou in the Western Zhou Dynasty, his son King Ping of Zhou came to the throne.As Haojing suffered war damage and was threatened by the Quanrong, in 770 BC (the first year of King Ping of Zhou), King Ping moved the capital from Haojing to Luoyi (today's Luoyang, Henan).At this point, the Western Zhou Dynasty ended and the Eastern Zhou Dynasty was established.From this year to 476 BC (the 44th year of King Jing of Zhou Dynasty), it was the Spring and Autumn Period.The Spring and Autumn Period is named after the chronicle of the Lu State - Spring and Autumn Period - written by Confucius. This history book begins in 722 BC (the first year of Lu Yin) and ends in 481 BC (the fourteenth year of Lu Aigong). It is the same as the Spring and Autumn Period.The upper and lower period limits are roughly the same.
