I'm sure it's not employment, it depends on you, but I've heard that in early 2023, Cumulus Education set up a "Yangtze River Delta Employment Service Center" in Nanjing, with employment services centered in Nanjing and radiating outwards, and the employment services are also very good, with employment instructors carrying out one-on-one career planning, CV modification, and interview counselling, and recommending targeted employment.

You can also learn the basics of self-study, and then to cumulus cloud and then systematic learning, because he is from learning to employment with the company in line, than the individual self-study to be too much better, but also very realistic.
