Can you actually ask about how something, an object, works, using làm việc?
Can it be also be a pseudo-system, as in the general daily grind of society?
"How to work this system?" Why not accept?
Because that is asking something different in English. Asking how does this work? Is asking how it functions. Asking how to work the system sounds lije you are asking how to scam the system or use it to unfair advantage
