In 281 CE the tomb of King Xiang of Wei (d. 296 BC) was opened, inside of which was found a historical text called the Bamboo Annals, after the writing material. It is similar in style to the Spring and Autumn Annals and covers the time from the Yellow Emperor to 299 BC. Opinions on the authenticity of the text has varied throughout the centuries, and in any event it was re-discovered too late to gain anything like the same status as the Spring and Autumn.
