Definition
雷打不动 is a four-character idiom that literally means 'unshaken even by thunder.' It describes plans, rules, schedules, or principles that are absolutely fixed and cannot be changed under any circumstance. You can use it to emphasize that something is non-negotiable or happens without fail — for example, a weekly class that runs every Sunday without exception.
