The patient's family members, "..."
The patient's younger brother was dumbfounded as he watched the special forces soldiers retrieve the money they had hidden in their wall. Then, in front of the camera, they flicked through the notes to show the serial numbers imprinted on them.
Chi Yang asked in return, "This number was issued not long ago by the Bank of Camino. You can determine the exact month of issuance by cross-checking the serial numbers with the Central Bank. So, how was your brother able to acquire these recently issued notes ten years ago?"
Seeing that the brother was about to retort, Chi Yang decided to end things quick because he not want to quibble with him anymore. He said, "Don't tell me that you went to the bank recently to exchange the old notes for new ones. You have to be aware that the bank is monitored. We can immediately confirm whether you have indeed gone to exchange notes recently.
This shut the patient's brother up.
