For over 50 years, SOTUS – a Hazing based system used for college initiation in Thailand – has been involved in Thai universities. It stands for Seniority, Order, Tradition, Unity, and Spirit. It is the system for freshmen to bring harmony to their friends and to show their pride through their institute. By seniors, freshmen have to do activities such as singing university songs. Moreover, freshmen are required to do a lot of things; for example, wear a nametag, and show respect to seniors. These requirements lead seniors to try to make their juniors do what they desire and punish them if they don't do seniors' orders.
