As a special ethnic group in Macao and an outcome of Oriental-Western cultural communications and inter-ethnic contacts, Macanese people are of great research value in sociology, ethnology and cultural studies. This article analyses the situations of three categories of the Macanese reunions, i.e. religious rituals, traditional celebrations and thematic celebrations. Four points are maintained in this article: a. religious activities as “rituals” are god–man and man–man interactions; b. with application of social media, traditional celebrations as “ceremonies” are “the invention of tradition”, old and new; c. homage to “model” and historic glories carry significant meaning to thematic reunions as “celebration”; d. cultural identity of Macanese people is an important premise for defining their ethnicity.
