Beijing's talent introduction policy usually requires candidates' academic qualifications and abilities, and English proficiency will also be one of the selection conditions. If you fail in CET-6, you need to improve your English first, including listening, speaking, reading and writing. You can gradually improve your English by attending training classes, self-study or communication. When the ability and level meet the requirements, you can sign up for the next CET-6 to meet the policy standards of talent introduction in Beijing.
At the same time, you might as well pay attention to other suitable talent introduction policies or positions in Beijing, some of which may require lower English level.
