About the on-the-job graduate students of law in Nanjing University, it is like this:

1. The Master of Laws does not require work experience, but the Master of Public Administration must graduate for three years before taking the exam.

2. Certificate non-academic education 10 month, dual-certificate academic education 10 month.

3. I suggest you go to official website, the Graduate School of Nanjing University, and check the on-the-job postgraduate enrollment brochure and professional catalogue. In case of doubt, it is recommended to consult the scientific research admissions office of Nanjing University directly.
