The word "rudder sound" comes from the term of China's ancient navigation period. At that time, when ships in China were sailing, they used the rudder to control the direction of the ship by turning, and each direction made a different sound. These sounds were called "rudder sounds" and were an important reference for the crew to help control the direction of the ship at that time.

The practical significance of rudder sound is to help the crew better control the direction and improve the safety of the ship at sea. At that time, because there was no modern equipment, sailors needed to rely on manual calculation and observation to change the course of the ship through the pronunciation of the rudder in order to cope with the changes in wind and waves. Therefore, rudder sound is a basic skill in ancient navigation and an essential skill for survival at sea.

The appearance of rudder pronunciation proves the height of ancient navigation development in China, which has profound cultural accumulation and historical value. Nowadays, rudder pronunciation has become a traditional culture and folk art, and many coastal cities and fishing villages have groups or individuals who inherit this skill. In addition, rudder pronunciation has also become a unique musical art form, which has been loved and appreciated by the audience.

Rudder sound is not only the representative of China's ancient navigation skills, but also an indispensable part of China's marine culture. The development history and cultural value of rudder sound make it an important marine cultural resource, which deserves further exploration and inheritance.
