The Shanghai Port is one of the world's busiest ports, and it has been leading in terms of trade volumes for many years. However, there is a sense of uncertainty surrounding the future of this port as several clubs have their own struggles to survive.

As for the clubs fighting for survival, they include the Guangzhou Evergrande, Wuhan e-Sports, and Shenzhen FC. All three teams are currently in danger of being relegated from the Chinese Super League. The relegation process can be tough, and it will require significant effort and hard work to ensure that these clubs stay in the league.

With regards to the Shanghai Port, it is important to note that the port's success is not solely dependent on its ability to handle large amounts of cargo. It also plays a crucial role in facilitating international trade and commerce, which helps to support the growth of the global economy.

In conclusion, while the Shanghai Port may be leading in terms of trade volumes, it is not immune to challenges such as the ones faced by the clubs fighting for survival. It is essential for all parties involved to work together towards finding solutions that will help these clubs stay in the league and continue to contribute to the global economy.
