What is the meaning of the underwater national gate opening

The opening of the underwater national gate, which originated from a legend in the history of China's sea defense, means that the underwater national gate has been opened. Historically, oceanic sea defense has been a great concern for the Chinese government, and the opening of the national gate underwater is an important part of traditional Chinese maritime culture.

According to historical records, during the Northern Song Dynasty, in order to defend the sea borders, the Song court ordered the construction of a mysterious project in the waters of southern Fujian, called the "hole gate", which was a method of controlling the entrance and exit of the strait by utilizing the topography and water currents.

Today, the opening of underwater gates and China's maritime culture have become an integral part of Chinese national culture. This mysterious story has been written into the history books and has continued and evolved over time, becoming one of the most important elements representing China's maritime culture, as well as reflecting the multiculturalism of the Chinese nation.
