The subject wants to ask "which is better, the village public salary of 3400 or the training institution salary of 3500?" The village public salary is 3400.

1. Public educational institutions are established and managed by the government and enjoy high stability and welfare benefits. Training institutions are unstable.

2. In public educational institutions, teachers have the opportunity to take the teacher qualification examination, promote their professional titles and participate in professional training, which can enhance their personal career development and professionalism. Training institutions have no chance to promote their professional titles. So the village public salary is 3400.
