高僧傳 9.29

9.29

黃河中舊不生黿，忽得一，以獻虎。澄見而歎曰：「桓溫其入河不久。」溫字元子，後果如言也。

Formerly, large softshell turtles were never produced in the Yellow River; suddenly one was caught and presented to Shi Hu. When Fotudeng saw it, he sighed and said: 'Huan Wen will enter the River before long.' Wen's courtesy name was Yuanzi; later things turned out indeed as he had said.
