Is it better to maintain software or develop software?

Each has its own advantages, but from an overall perspective, software development is better, maintenance is a later stage, and the technical skills required are not very strong. This is like a car manufacturer and a car repairman. As a worker, the type of work involved in building cars is definitely better than the type of work involved in repairing cars. A friend of mine lives in Suzhou, and he is also engaged in software development. Pretty good. Monthly salary starts at 5,000.
