Ling Huo didn't dare make Xi Ana wait any longer than she already have so he immediately took a shower after the emergency operation he had a while ago.
He told President Han to inform Xi Ana that she can wait in his office as he will be done soon so when he opened the door and found the person sipping tea inside he wasn't surprised anymore. "I apologize for making you wait, President Xi." in any circumstances, a person should apologize for making a person wait.
"You don't have to be so courteous Doctor Ling, it was inevitable since it was an emergency. This may be a little rude since this is your office but please sit down, Doctor Ling." Xi Ana smiled.
