别不快乐我会开心
[bié bù kuài lè wŏ huì kāi xīn]
The phrase 'Bie Bu Kuai Le Wo Hui Kai Xin' roughly translates to 'If you're not happy, I'll be glad'. However, its real implication may convey sarcasm or bitterness - if the ones close to me do not experience happiness anymore, at least I have my own peace of mind and happiness. This may come from a sense of independence, a bit of irony, but more often expresses self-mockery in humor.
