According to the information of Henan Tuhua Education, the proportion of "three supports and one support" entering the interview is 1:3, that is to say, if the position is recruited 1 person, three people will enter the interview. Only one person can pass the interview, not just the interview. The reason why the interview should be conducted according to this ratio is to reflect the fairness and justice of the examination and let more people have the opportunity to participate in the final competition.

"Three supports and one support" means that college graduates go to teach, support doctors, support agriculture and help the poor, and promote the development of rural grassroots social undertakings, so it also includes teachers' posts.
