The members patiently introduced the functions of the organizations, and enthusiastically learned the life of the freshmen at school and provided them many useful advices. That evening at seven o 'clock, a teach-in meeting was organized at the moot court, during which every department of the organizations gave brilliant presentation.Through the propaganda and teach-in activities, the new students had more opportunities to know the Youth League Committee and Student union of the school of Light Industry and Food Science.
