How can Fengshun substitute teachers become regular teachers?

I must wait for an opportunity. I am also a substitute teacher, and I am looking forward to the introduction of new policies by relevant departments. Now I look at more than two thousand teachers' salaries every month, and I am only a fraction of them. My heart is too unbalanced. Why do we work much more than them, but earn little! Live in their cynicism every day! When can we achieve equal pay for equal work? ! What is even more infuriating is that some normal teaching and scientific research rights have also been rudely deprived, and any honor such as advanced and academic leaders can only be within reach. How pitiful we are! Why doesn't the more hateful current education system give us a ray of sunshine to educate the disadvantaged groups?
