“书信”并非只是自纸黑字,它包含了两重涵义:“书”指函札、书札,即书信的语言文本;“信”指送信的使者,即所谓“信使”;二者构成一个有机整体,缺一不可。近代通讯技术产生之前,澳门与广州之间外国书信的传递成为世界与中国的纽带,也是世界近代邮政制度与中国传统邮驿体系的衔接与过渡。有关清代澳省间的客邮已有较为丰富的研究成果,但关于“信使”的研究却是一个空白薄弱环节。通过研究澳门与广州之间传递外国信件上的中文信息,使得活跃于澳省间的客邮信使浮出水面。这是从未被人提及的与外国客邮并行的中国地下民间邮递形式,伴随着中外商业网络而产生,以广州和澳门为主要据点,冒着被官府镇压的巨大风险,对中外商贸往来和文化交流产生了重要影响。作为澳门与广州之间复杂多变的邮递方式之一,这种灵活多变的客邮信使在与外国客邮合作交融过程中共同为澳门广州乃至整个岭南社会的发展做出了贡献。 “Letter ” is not only from the black paper, it contains two meanings: “book ” refers to the letter, book, that is the language of the letter; “Letter ” refers to the messenger of the letter, the so-called Messenger “; the two constitute an organic whole, are indispensable. Before the advent of modern communication technologies, the transmission of foreign correspondence between Macao and Guangzhou became the link between the world and China. It was also the interface and transition between the modern postal system in the world and the traditional post system in China. There have been quite a lot of research results about passenger mail between Qing dynasty and Macao, but the research on ”Messenger " is a blank link. By studying the communication of Chinese messages between Macao and Guangzhou, foreign guest messengers active in the province of Macao surfaced. This is a form of underground courier of China that has never been mentioned in parallel with foreign passenger ships. It is accompanied by a network of Chinese and foreign businesses. Taking Guangzhou and Maucao as the main points, it runs a huge risk of being suppressed by government officials. And cultural exchanges have had a significant impact. As a complex and changeable postal service between Macao and Guangzhou, this flexible passenger postal messenger has contributed to the development of Guangzhou, Guangzhou and even Lingnan society in cooperation with foreign guest crews.
