There was such an allusion on Earth that talked about how someone wanted to bribe their boss. The boss would say, "Someone else will find out about this matter. It is inappropriate." This person would then persuade his boss, "On Earth, there will only be you and me who know about it, no one else will know." The boss would then say with a sigh, "Heaven and Earth know, the gods and spirits know, you and I know, how can there be no one else who knows?"
Sui Xiong had little talent and limited knowledge, and he could not recall the exact content of this allusion. But that saying of, "Heaven and Earth know, the gods and spirits know, you and I know," was quite interesting, so he could remember that part.
