 The students were surrounded by armed troops upon reaching the academy's athletic field for morning exercise and told that they would be separated and taught different curricula if they were communists.With the exception of one student suffering from mental problems, no students stepped forward to identify themselves as communists, but the cadet commander announced that everybody's political views were known and the students were ordered to identify the communists in their ranks.The students separated out as communists were arrested and taken to the Nanshitou concentration camp when the remaining cadets were taken to their dormitories.
