What do you mainly study? If you know what civil law and civil procedure are, you should know what administrative law and administrative procedure law are. Civil law and civil procedure adjust the civil relationship between equal subjects, while administrative law and administrative procedure law adjust the relationship between the government and the people. For example, the government gives you a marriage certificate, the government gives you a business license, and the government gives you a real estate license. These are all administrative law adjustments. If you are dissatisfied with the government's behavior, you will be adjusted by the administrative procedure law.
