During the last week of military training, the instructors of each class began selecting the students who would take part in the assessment. Even though the selection was made based on performance, the students had a choice whether to participate or not.
Only thirteen students from the traditional chinese medicine department met the selection criteria, which was exactly the number of people required. Tang Xiaoxiao and Zheng Miao were one of the thirteen students who made the cut, so they registered themselves for the assessment.
