I believe it is not Chinese; the third symbol seems to be a Japanese "katakana" (sa).
Google Translator gives you an option to draw and check for ideograms.
Though the first 2 ones (or is it one ideogram as a whole?) I couldn't find which one would they be.
So perhaps it's not even Japanese, and the third one is just a coincidence (or the only one in Japanese).
Maybe it's just random drawings; though that third symbol is too much like the "sa" katakana in Japanese.
