《旧唐书·列传·卷三》
出潼关后，防备逐渐放松，李密请求买来酒菜，每天晚上吃吃喝喝，吵吵闹闹，通宵达旦，押送官员不把这当回事。
及出关外，防禁渐弛，密请市酒食，每夜宴饮，喧哗竟夕，使者不以为意。
After they left Tong Pass, their vigilance gradually relaxed. Li Mi asked to buy wine and food. Every night they ate, drank, and made a lot of noise the whole night long. The escorting officers did not take it seriously.
