If it is Beijing, I recommend Beijing Giant Times Education, an old enterprise with more than ten years' experience, which specializes in adult education. Its academic qualifications and environment are very good, and its reputation is also quite good. If you are not in Beijing, you can think about it. After all, there are many ways to get an adult education. After all, it is an institution in a first-tier city, which is more reliable, depending on your personal inclination.
