Resources listing polysyllabic Mandarin words with same pronunciation differing only by tones?
I suggest you use an online dictionary similar to this site: http://www.mdbg.net/chindict/chindict.php?page=worddict&amp;wdrst=0&amp;wdqb=shishi

The linked site above allows you to hear the pronunciation (click on the arrows), however I suggest you copy and paste two characters into Google translate which has the audio and it pronounces it as a set phrase rather than separately as the first site does e.g. https://translate.google.com.au/?hl=en&amp;tab=wT#zh-CN/en/%E6%97%B6%E4%BA%8B
