关于渤海国的亡国时间，一些史书载为亡于辽天显元年（９２６），学术界也多从之。本文作者考诸史书的不同记载，认为渤海国应亡于天显二年（９２７）元月，并对史书误载的原因做了探讨。 About the time of the nation's death in the Bohai Sea, some of the history books were found dead in the first year of the Liao Tien-xian (926), and many academic circles from there. According to the different records of various historical books, the author thinks that the Bohai Sea State should die in the first month (927 January) of Tianxian, and the reasons for the miscarriage of history books are discussed.
