have it both ways

​

to get advantages from two opposing things

两全其美，见风使舵

You can't have it both ways - you either work longer and get paid more or have more leisure time and get paid less. 你不可能两者兼得——要么工作长些报酬多些，要么休闲时间多些报酬少些。

You cannot have it both ways. You must either stay home or come with us.

你不可能一身二用，要不你留在家里，要不就跟我们一起去。
