Astronaut ['? str？ n？ (t) space pilots and astronauts

Astronaut? zm？ n？ : t] Soviet astronaut

Astronaut [talk? n？ : t] n. Space pilot, China astronaut (Chinese pinyin taikong and astronaut synthesis)

The first astronaut in the world was Gagarin of the former Soviet Union, so Astronaut should be the earliest Russian element used and applied. Then there are astronauts in America. They created astronauts in their own English. Astro is the prefix of outer space. China also had its own astronaut in 2003, becoming the third country in the world to have an astronaut. It uses neither Russian nor English, but Chinese Pinyin to create a new astronaut in space, which shows the respect and admiration of western countries for China's space cause.

Personal opinion, I hope it helps, O(∩_∩)O~
