After you take up public office, you need quite good work results (if possible, you will perform well and people will automatically recommend you for promotion)
Or you have to have enough money and get on well with your colleagues before you can take the next step.
Of course, if you have a strong background, none of the above is needed, but you said it all. . . . . .
In this way, my uncle became the captain of the anti-drug detachment.
In short, the officialdom is sinister and the people are sinister. The above is only basic, and it needs years of struggle and hard work.
Finally, I hope you can be mayor one day. In the name of the father, the son and the holy spirit, amen.
