people only treat you one way , the way you allow them to.
你的这个同事人品极差，这种垃圾人，就要怼回去。而且你没做错事，至少要为自己口头defend啊。
录音可以作为比较极端的方法但是未尝不可。
建议先直接面对这个同事说清楚. enough is enough! 之前让着你是我大度，不计较。This is a professional workspace but the way you treated me is not professional at all. If you want to be skeptical of my work, bring it on the table with my manager. If you want to mock at my height, why dont you try picking someone of your same size? I am nice to people who treat me with respect, but you certainly do not deserve so.
