One more chance to choose.
If the 12 year compulsory education policy is open, then all students will have the opportunity to enter the high school gate and have another choice. Different majors can be offered for students to choose freely in high school, and technical courses can be offered as elective courses.
Ease the employment pressure
In addition, the state can also raise the wages and benefits of skilled blue-collar workers. With the increasing employment pressure, some factories find it difficult to recruit people, and some companies have been laying off employees, which can also ease and balance the pressure on both sides.
Relieve parents' anxiety
Most importantly, 12 years of compulsory education can alleviate the anxiety of many parents, and also allow parents to have more working hours without running around for school.
