Mother Geng certainly couldn't answer her son's questions, repeatedly saying, "The doctor's clothes are white, their faces are similar, I can't tell who is who. Their words are mumbled, I can't hear them."
Geng Yongzhe asked again, "Did the doctor say when the surgery for my brother would be when they asked us to sign?"
"I don't know what date? Did the doctors say a date?" Mother Geng's response was that she couldn't even understand the date of the surgery, which seemed quite surprising.
Geng Yongzhe looked at his mother, a question mark appearing in his eyes as he wondered what was wrong with his mother's mind.
In fact, Mother Geng definitely didn't fail to understand the date, she simply didn't take it in, didn't form a memory chain in her mind, equivalent to nothing. For the brain to form a memory chain, conditions are needed, previously stated not to repeat.
