If you want to apply for zero-based human resources, it is recommended to study systematically. In fact, the qualification certificate of human resources is of little use and you can't learn much knowledge. It is recommended to apply for in-service graduate students in human resources and study systematically, such as Peking University, National People's Congress and Chinese Academy of Sciences. I recommend the on-the-job postgraduate course of human resources in the Institute of Psychology, Chinese Academy of Sciences. Integrating theory with practice and applying case analysis will certainly be of great help to your future work.
