It's harder to test. There is no national examination for teachers in Zhangjiagang. The difficulty of the exam is not only the embodiment of the difficulty of the exam itself, but also related to the number of candidates and the quality of candidates. The number of people applying for positions is often dozens or even hundreds of times that of the number of recruits, and the competition is fierce, so no matter what the content of the exam is, the difficulty of passing the exam will not be too low.
