There is something wrong with the choice you gave. There is no so-called inferior education at home or abroad. You can divide it into: basic education and higher education. The former includes primary and secondary schools, while the latter is junior college or above. If technical secondary school is added, it refers to the education in technical secondary school or technical school after 16 years old.

I don't know why you ask this question. Nine-year compulsory education is basic education, which was beyond doubt at that time. From other aspects, it should also be (attention is original, it should be, as for reality, let alone) national education, which is the comprehensive quality education for people and the education that people can transform into the most basic survival skills of workers. This is my humble opinion, encourage each other!
