In Hong Kong's universities and higher education institutions, orientation camps (Chinese: 迎新營), also known as “Ocamp”, are held by different student organizations in order to welcome new students before their first academic year. There are different types of orientation camps. “Big ocamps” (大O) are organized by the students' union or constituent colleges, while “small ocamp” (細O) are usually organized by faculty or departmental societies with a view to welcome students who study in the same faculty. The duration of ocamps is usually two to seven days.
