For professional divers, diving can be a job, an entertainment, or a great teaching career that allows more people to inherit and learn. Whether it is from the initial popularization of theoretical knowledge to hands-on assistance to students' practice, or from self entertainment to personal value enhancement in water rescue, salvage, and protection of marine ecology, as diving instructors, they will lead more people to freely dive in the ocean kingdom like fish, enjoying a variety of scenery while ensuring safety. For students, in addition to holding a flashlight that can give them the light of hope, the coach will also be their underwater hope and beacon, while the teams of those who come later will only grow like sparks, gradually mature, stabilize, and improve their abilities in every practice.

The road to exploring the mysteries of the ocean is long, but there is an eternal light accompanying those who travel together. Even if the night is long, they can still imagine freedom, dive into the mysterious and dreamlike kingdom, and leave their footprints in the world of the sea
