康乐 is a formal or semi-formal word meaning 'peaceful and happy' or 'well-being and joy.' It often appears in fixed expressions like 康乐活动 ('recreational activities') or 康乐中心 ('recreation center'), pointing to structured leisure or wholesome community recreation. As a stative verb (s.v.), it describes a state or quality and is typically used attributively or in compound nouns rather than as a standalone predicate in everyday speech.
