1. I don't know what skills primary school teachers should have, and the training objectives lack scientific standards.

2. The basic skills training level of primary school teachers in pre-service training has declined, and the vocational skills training of high-level teachers has been ignored.

3. The pre-job training of primary school teachers' vocational skills is scattered and lacks standardized management.

4. The pre-service training methods of primary school teachers' vocational skills are outdated and single, and there is a lack of targeted guidance and supervision in the training process.
