At present, there are many interview training institutions in Haikou, such as Zhonggong, Tuhua and Haidayuan. I once accompanied my classmates to Haidayuan for consultation, and I felt quite reliable. It is run by teachers from Haida University, with a strong faculty, many of whom are professors, masters and interviewers from some large enterprises. The class place is in the campus of Haida University, with convenient transportation and good environment. I hope my answer is helpful to you.
