Not necessarily. The enlistment notice was an invitation issued by the army to eligible citizens, but it did not mean that everyone who received the enlistment notice could successfully become a soldier. After receiving the notice of enlistment, they had to follow the instructions and complete a series of registration, physical examination, interview and other procedures. If they met the requirements of the army and passed the assessment, they could officially enlist. However, enlistment was not the only option. Citizens could also become a soldier through other means, such as the college entrance examination, independent selection, postgraduate entrance examination, etc. It was important to note that the enlistment notice was only a necessary condition for enlistment, not the only standard. If they didn't meet the requirements of the army, they wouldn't be able to enlist even if they received the enlistment notice.
