The paper analyzes an online lesson on Chinese music provided by the Polish Ministry of Education for use in secondary schools within the context of the Ministry’s official school program. It also briefly discusses the state of academic Chinese studies in Poland. A detailed examination of the lesson reveals factual errors, a mix of historical and legendary facts, misattribution of classical texts, and chaotic transcription of Chinese words, among other issues. Academic sources were not consulted; instead, the lesson is based on a 19th-century book, Britannica, and Wikipedia articles (including mistakes that had been corrected years ago on Wikipedia). The use of the text and illustrations is also questioned. None of the sources are referenced, possibly violating the moral rights of the authors, even if they waived their financial rights (e.g., by using a CC-BY-SA 3.0 license). The authorship of the main illustrations is attributed to “Online-skills” (the company responsible for creating the lesson), and the files have had their EXIF data erased. These illustrations are virtually identical to those from the Wikimedia Commons repository, where the authorship and EXIF data are preserved. The findings raise serious concerns not only about the factual quality of officially sanctioned online resources but also about the moral lessons inadvertently conveyed to the students.
