[1] The Jinshu 晉書 (Book of the Jin) mentions this same incident, dating it to the fifth month of the fifth year Yongjia (3 June to 2 July, 311 CE; under the Western Jin), and reporting a response, linking such anomalous births to military chaos. See Jinshu 29.909:

五年五月,枹罕令嚴根妓產一龍,一女,一鵝。京房易傳曰:「人生他物,非人所見者,皆為天下大兵。」是時,帝承惠皇之後,四海沸騰,尋而陷於平陽,為逆胡所害,此其徵也。
