Which countries embed politics in every subject like China?
I learned a very interesting phrase in China: 课程思政(Ideological and Political Theories teaching in All Courses, starting from 2014, an idea of Shanghai municipal government) where every knowledge point in every subject should relate to politics.
For instance, this chapter about DNA in biology:
It says that communism's DNA is to serve the people and govern the country forever.
I wonder if only China applies this method? Or there are some other countries doing it also?
