The advantage of vocational schools is that practice is more than theory. For students who don't like learning, changing a learning mode can bring students a sense of accomplishment. Another advantage is that the students trained by vocational school students are professional, and many secondary schools arrange jobs. The salary that mature secondary schools find for their children is not lower than that of undergraduate courses, while ordinary high schools do not have this advantage. Children study hard, and the pressure is so great every day, depending on the college entrance examination these two days. If you fail the exam in those two days, your three years' efforts will be in vain, but vocational schools are different. As long as you study hard, how much you learn means how high your salary will be in the future, which is in contrast to your efforts.
