杨成武同志的一篇回忆文章提供了这样一段轶事。有一次,周恩来去机场为一位外国元首送行。就在这位国家元首的飞机“腾空”以后,外国使节的队伍依然整整齐齐,而我国政府的几位部长却离开队伍走向汽车。周总理严肃地对杨成武说:“成武,把他们叫回来,飞机还要在机场上空盘旋一周才走!”事后,周恩来对这些部长们提出了批评,他说:“国家元首的座机起飞后绕场一周,是表示对所到国的答谢,东道国送行的人是不能在这之前离开的,离开了就是礼貌不周。” A memory article by Comrade Yang Chengwu provides such anecdote. Once, Zhou Enlai went to the airport as a foreign head. Just as the head of state’s aircraft was “vacating”, the ranks of foreign diplomats remained neat and the few ministers of my government left the ranks and went to the car. Premier Zhou solemnly said to Yang Chengwu: “Coming into arms, calling them back, the plane has to circumnavigate the airport for a week before leaving!” Afterwards, Zhou Enlai criticized these ministers. He said: “After the departure of the head of state Circling a week means that thanks to the country you visited, those who sent the host country can not leave before this time, and you are left with politeness. ”
