English as a global language has made great impacts socially and communicatively on widespread levels. With the increasing use of English as a lingua franca (ELF), associating English with purely native English speakers seems no longer appropriate. Instead, English is linked with users in its global community. With ever growing English users worldwide, acquiring the intercultural communicative competence (ICC) becomes a must in English language teaching (ELT). However, theories in this field have scarcely been put into practice. Empirical research exploring English learning experience, intercultural communication and practices of Business English majors remains scant in China. This study involved 98 Business English majors from a vocational college in the southeast part of FuJian Province. They volunteered for interpretation services at the Cross-Strait Floral Exposition in November 2019 between international exhibitors and local tourists. The reflective journals of each of the 98 students as well as ten semi-structured interviews were used for the qualitative analysis. During the exhibition, the participants applied the English they learned from classrooms to a real-world communicative setting. They also practiced the first-hand concept of Global Englishes (GE) and developed the ICC. This whole experience highlighted the importance of teaching Business English in a practical situation. Recommendations were made for Business English education at a tertiary level based on the results. To prepare Business English students for their future careers, English professors should master and disseminate GE pedagogy and develop their students’ ICC related skills.
