“…According to Liao’s (2011) thesis, “A study on intermediate spoken communication course for business Chinese: Analysis, design, and implementation,” learners are highly affirmative of the teaching design for business Chinese oral communication, and this method allowed learners to accurately grasp the deeper meaning of speech acts, to cultivate capabilities of appropriate responses, and to immerse in real business Chinese situations. Vu (2011) found that the Vietnamese learners of Chinese have a strong demand for “business Chinese,” and they expect to study “authenticity” in business Chinese textbooks, as discussed in Vu’s thesis, “The Research about the need and development of business Chinese in Vietnam.” In connection with the assessment indicators for business Chinese materials, Chung (2018) constructed 43 evaluation indicators categorized into material content and design, based on 5Cs (Communication, Cultures, Connections, Comparisons, and Communities), for business Chinese textbooks. Liao (2019) adopted the Fuzzy Delphi method to construct 33 evaluation items, including learners’ needs, material content, teaching objectives, and audio and video presentation.…”
