What are the admission requirements for Wu Wen schools in the Southern Song Dynasty?

Wu Wen School in Southern Song Dynasty is a full-time, full-boarding, closed and sub-military modern school covering preschool education, compulsory education, Chinese studies education, vocational education, psychological consultation and martial arts education and teaching. According to the information I have found, Wu Wen schools in the Southern Song Dynasty did not have clear admission requirements, but they needed to meet the admission requirements, such as age and physical condition. If you need more information, I suggest you contact the school directly for consultation.
