It is said that it has reached 4% this year, and some people are very upset and don't know how to spend this large sum of money. As far as I know, China should have achieved this goal as early as 2000, but it has been delayed for fifteen years, and it is speechless. In the 1990s, the United Nations proposed to reach 6%. China has long been one of the lowest countries, was and still is. Now it seems that other countries spend a lot of money on paving the way for education. I guess it is because they don't know how to spend it.
