The first point is the cost of your career change, your current job and your current development prospects, the influence of your family or relatives on you, especially the economic impact, which have to be seriously considered. After the job change, the assistant's salary is about 2000 yuan, and there will be no promotion for some time.
The second point is the process of changing lines, that is, the acquisition of this assistant card. The common practice now is to find some training institutions and participate in the training. During the training, there will be courses and internships. After the training, a diploma will be issued. With this diploma, you can take the qualification examination. The training cost {assistant} is generally 5000-5500 yuan, and the training time is almost one year. At present, I haven't heard that I can read a few books and then find an internship with the seal of the unit (please forgive me, I may not have heard of it, and I haven't seen anyone in this field).
Third, it is the development prospect after the career change. This assistant can only have a bachelor's degree, but if you want to be more advanced, it is either a degree or a mixed degree. This is a development prospect. The higher the level, the higher the training cost.
In addition, I'll give you some suggestions about training institutions. For example, there are some training institutions in Wuhan, Shenzhen and Henan. You can consult them. There are also some websites: China Vocational Qualification Examination Network, Zhiyi.com, Ministry of Labor and Social Security, Provincial Personnel Examination Institute, China Personnel Examination Network, etc. This kind of information can be consulted online or by telephone.
