陈兰彬是清季首任留学生监督和首任驻美公使。在走出国门办理洋务的过程中，既表现了传统士大夫的保守和对世界大势的隔膜，其又在忧患意识与忠君报国思想的驱使下，在中西交往的最前沿做了一些维护国家主权的工作。 Chen Lanbin was the first student monitor in the Qing Dynasty and the first U.S. ambassador to the United States. In the course of going abroad and going through the Westernization Movement, she not only demonstrated the conservativeness of the traditional literati and the separation of the great powers in the world, but also made some efforts to safeguard state sovereignty at the forefront of the Sino-western exchanges, driven by her sense of urgency and the idea of ​​serving the country by loyalty to the kingdom .
