I always mix up their tones and/or meaning. Do you know a good mnemonic to differentiate the two?
Maybe there are compound words which contain either character which could help me?
I found 买卖 which I get right tone wise (mai3mai5) and meaning wise (buy and sell) mostly. So I can connect tone and meaning using that. But when writing I still don't know where the 十 goes.

on top to be "+ income", that's how I remember :) as for how to remember the tones, that's just rote in a lot of cases. – Ming Oct 9 '14 at 8:21
