The answer to her question

Jiang Yue folded the paper and put it in her uniform skirt's pocket. 

She was just about to stand up when a hand suddenly grabbed her arm, causing her to halt in her place. 

She turned towards the man who was still blankly staring towards the wall, if it weren't for the hand that was still grabbing her arm, she would have thought it was all her imagination. 

"Father..." Jiang Yue softly called out and touched her father's hand. 

Seeing that he's still once again not reacting, Jiang Yue lowered her head, she thought that it probably was just a moment of unconscious action from him. 

Just like how he held Jiang Xiu when they visited him during their birthday. 

He should be able to communicate his thoughts in some bodily actions based on their latest examination of him, however he's suddenly going back to his condition before where he barely reacts which really leaves her confuse.
