From November 5 to 10, the 7th China International Import Expo (CIIE) was held in Shanghai. CCCC participated in the event, signing agreements with suppliers from 14 countries worth over 26 billion yuan.

CCCC Chairman Wang Tongzhou attended the opening ceremony, while Vice General Manager Pei Minshan and General Accountant Liu Zhengchang participated in related activities.

The Shenzhen-Zhongshan Link, a representation of new quality productive capacities, was showcased at the CIIE.

An integrated mega sea-crossing project comprising bridges, artificial islands, immersed tunnels, and underwater interchanges.

Through a combination of multimedia display screens and models, the achievements of the Shenzhen-Zhongshan Link were showcased, focusing on its three main components: the immersed tunnel, artificial islands, and main bridge. The exhibition highlighted the project's advanced construction techniques, technological innovations, and social value.

The application of digitalization and BIM technologies enabled the seamless integration of over 20,000 aluminum panels of varying sizes into the facade of the west artificial island. The leveling vessel Yihang Jinping 2, known as the "underwater 3D printer," and the immersed tube transportation and installation vessel Yihang Jin'an 1 ensured the tunnel's high-efficiency and precision construction.
