'The five planets moved in disorder, at midnight stars fell like rain, the earth shook, the Yi and Luo dried up' in Jie's 10th year (1580 BC by the current text)
Current text, Jie year 10: 五星錯行夜中星隕如雨○地震○伊洛竭. Wang Guowei gives no older source for the planets and falling stars ('at midnight stars fell like rain' is word for word the Chunqiu entry for 687 BC); 'the Yi and Luo dried up' is from the Guoyu ('in the past the Yi and Luo dried up and the Xia fell'), which gives no year. Pankenier reads the planet line as a memory of the planet gathering of 1576 BC.
