The reason for the shutdown of Longqing Switch attracted widespread attention at that time. This article will analyze this event from three aspects: historical background, technical reasons, and policy factors, in order to reveal the real reasons behind it.

I. Historical Background

Located in Tongzhou District, Nantong City, Jiangsu Province, Longqing Switch is an important waterway connecting the Yangtze River and the Yellow Sea. In the late Qing Dynasty and early Republic of China, Longqing Switch was one of the main channels for China's foreign trade. However, due to various reasons such as wars, natural disasters, etc., the operating conditions of Longqing Switch gradually deteriorated. In 1927, the National Government took over the management of Longqing Switch.

II. Technical Reasons

The main reason for the shutdown of Longqing Switch was that the technical level at that time could not meet its operational requirements. The ship lock system of Longqing Switch adopted steam-driven technology, which was quite advanced at that time, but gradually fell behind modern technology over time. In addition, there were also some design defects in the ship lock system of Longqing Switch, such as insufficient gate numbers, unreasonable gate heights, etc. These problems all exacerbated the safety hazards of Longqing Switch.

III. Policy Factors

In addition to technical and historical reasons, policy factors were also important reasons for the shutdown of Longqing Switch. During the Republic of China period, China was in a volatile political situation. In order to respond to domestic and foreign challenges, the National Government took a series of measures to develop the economy and strengthen national defense. However, these measures often ignored the importance of infrastructure construction, especially for key facilities like Longqing Switch. In addition, the National Government also faced competitive pressure from other countries, which also led to the continuous rise of operating costs for Longqing Switch.

In summary, the reasons for the shutdown of Longqing Switch are multifaceted, including historical background, technical reasons, and policy factors. This event reflects the backwardness of infrastructure construction and the instability of the political situation in China at that time. Although Longqing Switch has been shutdown for many years, it is still an important landmark building in modern Chinese history.
