A woman wearing a pink cardigan and dark pants stands in front of a classroom screen and points at the displayed content. The screen features a vocabulary lesson, focusing on tone collocation in disyllabic words. Three example words are presented with corresponding images: "gōngyuán" (park) showing a forest, "jīchăng" (airport) with an airplane illustration, and "chēzhàn" (station) depicting a train station. There are blank lines next to the words, seemingly for filling in additional information.
