Among the many laws and regulations, we have screened out the ones that have been abolished and selected the latest, authoritative and comprehensive ones. However, some provisions of some laws and regulations are not suitable for the current situation, but no new ones have been promulgated. We cannot make changes without authorization, so we have to retain the original provisions, but the appendices have corresponding supplementary amendment opinions or notices. Many laws and regulations are classified and combined according to different content and audience characteristics, and the supporting packages are optimized. The entire set of legal popularization books is very comprehensive and systematic, with strong learning, practicality and guidance. It is very suitable for legal education and practical guidance in rural and urban areas. In short, it is a good reading book for the "Seventh Five-Year Plan" legal popularization in the whole society.
