How to treat the construction of the new diplomatic system in the late Qing Dynasty?

Before the Opium War, China's diplomacy had an obvious concept of "going abroad for summer vacation" and disdained equal exchanges with foreign countries. At this time, there was no formal diplomatic system, no specialized diplomatic institutions and no full-time officials. After the Opium War and the invasion of foreign powers, China began to connect with the international community at the institutional level, especially in the diplomatic field. From the Prime Minister Yamen in the late Qing Dynasty, Minister Beiyang, and the Ministry of Foreign Affairs to the Ministry of Foreign Affairs in the early Republic of China, countries were first forced to set up permanent embassies in Beijing, and then ambassadors abroad, and the first overseas consulate was established in Singapore on 1877. This series of changes reflects the characteristics of China's gradual integration into the international community and going abroad in the process of becoming a semi-colonial and semi-feudal country, and actively learning from the western diplomatic system, which made China's modern diplomacy gradually professional and standardized, promoted the progress of the diplomatic system and promoted the modernization process of China. However, China's modern diplomacy was humiliating. China lost a lot of territory and sovereignty and paid a lot of compensation in the signing of unequal treaties that humiliated the country, which reflected the characteristics of China's weak national strength and political turmoil at that time. However, China's diplomatic system in modern times was transplanted from the west under the severe national crisis. At first, it showed many disadvantages. Many bad habits of feudal officialdom were widespread in the early diplomatic institutions of modern China, reflecting the characteristics of the times when tradition and change were intertwined and tradition was gradually overthrown in the late Qing Dynasty.
