Does baijiu go bad?

I'm curious, does baijiu, the traditional Chinese liquor, ever go bad? I've heard it's aged for years, but does that mean it can deteriorate over time if not stored properly? Is there a specific shelf life or storage conditions that need to be met to ensure it stays at its peak flavor and quality? It would be great to have some clarity on this matter, as I'm considering investing in a few bottles to appreciate in the future.
