Well, truth is, there's no hard and fast rule on how often each and every person should wash up.

事实是，没有硬性规定每个人多久洗一次澡。

But beyond that, there are no hard and fast rules about what is or isn't appropriate - it all depends on the recruiter.

但除此之外，没有硬性规定什么是合适的什么是不合适的——这完全取决于招聘人员自身。

Although you might think taking a daily shower should be part of your cleaning ritual, there's no hard and fast rule, although dermatologists agree that as a society, we shower too often.

尽管你可能认为每天洗澡应该是你清洁习惯的一部分，但这并没有硬性规定，而且皮肤科医生也认为我们洗澡太频繁了。
