Pre-service education refers to the adaptive training and ideological and political education organized before the scheduled recruits formally join the army. Time is not less than 7 days. The main purpose is to make the scheduled recruits adapt to the pace of army life in advance, help the scheduled recruits lay a solid ideological foundation for joining the army and serving the country, and master the actual performance, ideological foundation and hidden diseases of the scheduled recruits in detail through centralized management, education and guidance, physical review, etc., so as to facilitate the military service organs to select the best soldiers. When young recruits participate in pre-service education, they need to prepare corresponding personal belongings and follow strict management regulations. For example, prohibited items, such as various drugs and obscene articles, are all prohibited. At the same time, communication tools such as mobile phones will be managed centrally at the time of registration and will not be returned until the end of education. During the pre-service education, the time schedule is very tight. From getting up at 6 am to going to bed at 9 pm, the time schedule is very substantial. In addition to queue training and physical training, it also includes visiting Red Education.
