The lift

Secretary Han was stopped by Grandma Qing making him unable to inform Qing Shan about anything. 

Grandma Qing eyed Secretary Han to go out of the office and leave them alone. Understanding that it must be some family matter, secretary Han complied. He closed the door and made sure to put a DND board outside it. 

Hearing the voice of door closing Qing Shan frowned. He thought Secretary Han would say something. He raised his head to look at the closed door making his eyes pass through Grandma Qing inadvertently. 

"Grandma!" Qing Shan spoke and quickly got up from his chair. 

Grandma Qing smiled and waved her hand asking Qing Shan to sit while she herself walked towards the couch to take her seat. 

Qing Shan did not sit and questioned, "Is there something important Grandma? you should have called me.' He said worriedly.
