Background] Publications on the professional occupation of Requirements Engineering (RE) reported on market demands for both RE and non-RE qualifications and indicated the state-of-the-practice of RE roles in industry. However, prior research was not from the perspective of the RE area in the Software Engineering Body of Knowledge (SWEBOK). Nor, they shed light on the industry needs of RE professionals in China. [Aims] This paper focused on RE-specific tasks and skills sought after in China, from the perspective of RE activities elaborated in SWEBOK. [Method] Using an empirical qualitative research method, we selected and analyzed 535 job ads from China's two largest job portals.
