Niu Qingshan was somewhat stumped because, according to the law, a will wasn't valid unless it was signed by both the testator and two witnesses. The testator must sign in the presence of two witnesses then each witness must then sign the will themselves.
Therefore, even if Niu Qingshan wanted to help Cao Dequan to lie, he didn't know where to find two witnesses willing to perjure themselves to sign.
When Niu Qingshan explained the issue, Cao Dequan listened with a smile and said: "I'll find the witnesses myself."
Niu Qingshan, said cautiously: "What, if Chairman Ling Lao suddenly awakens? If he finds out what we did we will go to jail!"
Cao Dequan smiled and calmly said: "You can rest assured that the old guy won't wake up in this life. Even the doctor has said that his brain tissue has already experienced serious exhaustion, even if he doesn't die, he won't awaken unless there is a miracle."
