The Ministry of Higher Education of China has put forward the fundamental goal of cultivating talents with moral integrity and character in higher vocational colleges, requiring the cultivation of high-quality and highly skilled individuals who possess comprehensive development in morality, intelligence, physical fitness, aesthetics, and labor skills. This implies that students should not only possess broad and solid foundational knowledge and proficient professional skills but also exhibit sound and noble character traits. They should possess an innovative spirit, thinking ability, creative capacity, learning aptitude, and transfer-ability to adapt to the era and societal development, ultimately developing these abilities into professional qualities. This requires the curriculum to make the necessary teaching reform to achieve the purpose of cultivating professional quality. This study is to explore how to build a general education course based on professional quality education in higher vocational education and to analyze its impact on students’ professional quality. Through a case study of the Etiquette and Cultivation course, the study examined how such a general education course based on professional quality education can help students develop the necessary skills and qualities in their careers.
