第二次鸦片战争中,英法联军攻进北京,在圆明园被毁的余烬中,清政府与侵略者交换了《天津条约》。从此,外国使节可驻扎北京,其通信不受干涉,可自雇信差,也可要求中国政府负责寄递。这样一项被西方各国视为互相给予的外交权力,竟然成了中国新式邮政得以发轫的一个外因。 During the Second Opium War, the Anglo-French coalition forces attacked Beijing and the Qing Government exchanged the Tianjin Treaty with the aggressors during the destruction of the Yuanmingyuan embankment. Since then, foreign diplomats can be stationed in Beijing, their communications without interference, self-employed letter of credit, may also request the Chinese government responsible for delivery. Such a diplomatic power, viewed by all Western countries as giving each other a diplomatic power, has even become a cause for the development of the new postal system in China.
