After the person in front of Yao was arrested, how was his coin found?

It was simply found in this unlocked drawer below his office, just that simple.

Many times, the truth is quite speechless.

What is presumed is completely different from the truth.

I once went to a leader to handle some matters, feeling anxious with a gift in hand, only to find that when I entered his office, the cabinet behind his desk was piled high with various gifts (of course, all of limited value).
