Definition
大修 is a noun meaning a major overhaul or heavy repair, typically applied to machines, vehicles, buildings, or large-scale equipment. It's used as an object of verbs like 进行 (to carry out) or 需要 (to need). Do not use it as a verb — the action is expressed by a separate verb (e.g., 大修汽车 is not correct; say 给汽车进行大修).
