A friend is a male coach, but his career is different. What will happen? In fact, he is a working people who are not as good as migrant workers. Fitness coaches are not coaches of national sports such as basketball, volleyball and martial arts, but they are not as good as car coaches. So it's no advantage to find a fitness instructor to show off. It's a very unstable career. Of course, revolutionary work, regardless of rank, serves the people and is glorious as long as it is decent.
