Hello, in fact, you already have the answer in your heart. As you said, there is really no room for growth in special police. Although the welfare benefits are relatively stable, there is not much growth. As long as you don't like the work of special police very much, it's not very interesting to live like this. As for engineers, wages can go up, positions can go up, and development prospects are good. And the starting salary is not lower than that of the special police, and it will only be higher in the future. If you do well, you don't have to worry about losing your job. Therefore, it is recommended to choose engineers.
