After experiencing a whole new culture and transformed by it, those who return from oversea studies often find it difficult to adapt into local life. Psychologist points out that the longer their stay and the deeper their integration, the larger the cultural shock. They have four strategies: separation, integration, marginalisation, and assimilation. What would they choose?四名海歸（外國回來的留學生）的心路歷程。他們往外國留學，遇上全新文化衝擊，受異國文化影響，回港後發現不能重新適應本土文化，產生陌生的感覺，形成逆文化衝擊。心理學家指出，海歸在外國的年期愈長，以及融入的程度愈深，回港遇到的衝擊就更大。海歸處理的態度在四個層面體會出來：分隔、融入、邊緣化和被同化。他們會選擇哪一個呢？
