《旧唐书·列传·卷八十二》
皇帝已听说李抱真去世了，就派第五守进任使者坐传车去观察情况，并命将军中事务交给大将王延贵掌管。
上已闻真疾病，请见明日。如此者凡三日，缄乃出造中使，左右皆陈兵，甚严备。
The emperor had heard that Li Baozhen was dead, so he sent Diwu Shoujin to serve as an envoy in a sedan chair to observe the situation and ordered the general affairs to be handed over to the general Wang Yanguo.
