Why do only certain font switches work in math mode?
If my codes have a statement like ${bfseries{emph{something}}$, it will return an error:
bfseries invalid in math code.
But if I change the order of the control sequences, like this ${emph{bfseries{something}}$, everything is fine. Why is that?

Welcome to TeX.SX! You can highlight code in your post using back-ticks. To highlight code-blocks, either indent them by four spaces or use the{}on the gui.

@JouleV.Yeah,I also know that key word, but it only works in English.

Did you use a language other than English? If so, did you usebabel? Or did you usexeCJK?

emph is defined to be a "text command" and therefore sets its argument in text mode. That's why you're allowed to use
$emph{bfseries <stuff>}$
since bfseries occurs within text mode. The other way around,
$bfseriesemph{<stuff>}$
bfseries occurs inside math mode, which is not allowed.
If you want to set text in bold inside math, consider using textbf{<stuff>} or text{bfseries <stuff>} if you're using amsmath. If you want bold math content, you can use mathbf. Alternatively, if you want bold italic math content, use $bm{<stuff>}$ and also add usepackage{bm} to your preamble.
Note how bfseries is used above; there is no argument. That is, {bfseries ...}, not bfseries{...}.
