Abstract: Acculturation, a popular but important concept in intercultural communication studies, has been mainly concerned with a
sojourner's adaptation in a new culture that is different from one's customary one. With the increase of the overseas students from South
Asia and South Eastern Asia, studies on overseas students' learning of Chinese, and their acculturation in China have received great
attention. However, no individual among the vast sojourners has been singled out for deeper and more detailed investigation as to what
has been taking place along the way he or she adjusts and accustoms to the new culture. With the individuality of acculturation in mind,
this case study looks at the four stages and their related key events in his process of acculturation, that is, culture shock resulting from
typical Chinese food, a popular greeting "Hi", the strong motivation for learning Chinese to build personal networks, and the starting of
business cooperation between China and Sri Lanka. It is hoped that this case story will shed some light on the individuation process of a
sojourner when living and studying in a foreign situational context.
