According to annual statistics from the Hong Kong Immigration Department (ImmD), the number of mainland student visas approved for study in Hong Kong exceeded 35,000 in 2023. Meanwhile, the proportion of non-local students at University Grants Committee (UGC)-funded institutions has been edging closer to the 20% cap under the relaxed policies of the Education Bureau (EDB). As large numbers of mainland undergraduates converge on City University of Hong Kong (CityU), their cultural adaptation does not follow a linear path but instead displays a pronounced U-shaped oscillation. Enrolment data published by the UGC in 2023 show that mainland students account for more than 85% of non-local undergraduates at CityU. A longitudinal cross-cultural study by the Department of Psychology at the Chinese University of Hong Kong (CUHK) further indicates that the acculturation curve for mainland students in Hong Kong records a distinct anxiety peak at the fourth month. The three cases documented below, combined with internal tracking data from CityU’s Student Development Services, unpack the integration mechanisms across language, academic, and career dimensions.
Case 1: The “Completion–Application” Gap in Cantonese Courses and Academic Spillover
Chen Jing (pseudonym) is from Hebei Province and entered CityU’s Data Science programme in 2021 with a Gaokao science score in the top 5% of her province. Before enrolment she had never systematically studied Cantonese but believed the English-medium instruction would lessen the need for the language. In practice, Cantonese proved far more pervasive than expected—in group projects, internship interviews, and everyday social interactions. The Cantonese Survival Kit, an introductory course offered by CityU’s Language Centre for mainland students, had 240 places in the 2022/23 academic year. It received 312 registrations; 212 students completed all ten sessions and the oral test, yielding a completion rate of 68%. Chen was one of the completers, but she found the content concentrated on greetings, ordering food, and transport, failing to cover the rapid code-switching and colloquial slang that surface in academic discussions. This “completion–application” gap kept communication anxiety alive well into her second semester. Her first-semester GPA was 2.8. Through immersive practice in a Cantonese drama club and weekly conversations with a local buddy, her GPA recovered to 3.2 by the second semester. Yet the direct academic payoff of Cantonese remained limited: in the general education course “Social Change in Hong Kong,” case discussions were held in Cantonese; although assessment could be submitted in English, she lost substantial marks for class participation. By her third-year summer internship at a data mining company, her listening comprehension sufficed for regular meetings, but client calls still required handover to a colleague. This points to a structural gap between classroom Cantonese completion rates and real-world application contexts, one that calls for institutionally provided advanced Cantonese workshops with greater situational depth.
Case 2: Academic Writing Transition and the Fourth-Month U-Shaped Turning Point
Zhang Zijian (pseudonym), from Guangdong Province, studied an international curriculum in secondary school and possessed near-native English proficiency. He assumed a smooth academic adjustment and earned a 3.5 GPA in his first semester. However, as courses shifted from introductory surveys to advanced study, at the start of the second semester—the fourth month of his degree—he discovered his writing remained at the level of argumentative short essays, whereas Hong Kong programmes demanded analytical essays that engage multiple theoretical dialogues and demonstrate methodological reflexivity. His GPA slid to 2.9 in the mid-term tests of that fourth month, accompanied by insomnia and a growing tendency to avoid group activities. A cross-cultural psychology team at CUHK (2022) tracked 247 mainland students and identified the fourth month as the point of highest distress on the General Health Questionnaire (GHQ-28) and lowest academic self-efficacy—a U-shaped trough consistent with Zhang’s timeline. He subsequently received individual tutoring at CityU’s Academic English Centre, systematically studying genre analysis and refining stance-taking techniques for literature reviews. By the third semester his GPA recovered to 3.4, and his assignment for a regional studies course was nominated for a departmental best-paper award. His GPA trajectory formed a V-shaped pattern (3.5 → 2.9 → 3.4). Regular monitoring shows that around 62% of surveyed mainland students experienced a similarly significant dip around the fourth month, but only one‑third of them fully regained their first‑semester highs before graduation. This points to a need for institutional intervention that extends beyond start‑of‑
