Part of the fun in learning diving is that you will learn a complete set of new language. You will learn what “buoyancy” means, what “ residual nitrogen” is, what “ decompression dive” means. If you are getting your certificate in places like Phuket or Bali, you will learn everything in English. That’s great. Feels like you are sailing right into the global network of divers. No more barriers. You and millions of divers worldwide would be able to speak the same language instantly. That is so important. Especially for us Chinese who are bound in our own language in almost every aspect of our lives.
