The first half sentence is basically correct. Knowledge is power. For the same person, knowledge will create greater productivity than no knowledge. From the perspective of higher education, national competition is the competition of comprehensive national strength, and talents are an important part of a country's comprehensive national strength. Education is very important for cultivating talents, and top talents are the core competitiveness of a country, which shows the importance of higher education. Look at that powerful country. There are few world-famous universities. From the perspective of basic education, the improvement of the level of universal education will greatly promote the improvement of the productivity of the whole society. In addition, investment in education is a decreasing process. The education of previous generations needs a lot of investment, and the investment of later generations will be much less, and the education level will only improve rather than decrease.

The second half of the sentence is somewhat one-sided. Excellent teachers are also part of the investment in education, but to revitalize education, teachers alone are not enough. First of all, ZF should invest a lot, make a good plan and attach great importance to it. Teachers are only the last link, and teachers alone can't play a role.
