12345 is writing a letter of complaint a petition?

12345 is not a panacea, some problems can be solved quickly, and some problems cannot be solved.

12345 is just a communication platform, which belongs to the service of letters and visits. If your question involves a government department, he will refer it to the relevant department for specific solution. Then the relevant departments will give treatment advice, and this will be solved.

For example, I have complained about street lamps, and the traffic lights at intersections are useless. These problems will be solved in time and effectively.

But some problems are not easy to solve, and even need to be handled by the court.
