The wards and the Intensive Care Units of Family Mu's Hospital were forbidden to intruders. The hospital was known for the privacy and security which it provided to its patients. Apart from being providers of world class healthcare, they prided themselves on their ability to give patients the kind of privacy they needed, in order to heal.
Although Mu Qing was friendly and easy going by nature, he was never casual about his work. He took his profile and the hospital's reputation, very seriously.
He was inspired to become a doctor, by his grandfather, who was a doctor too. He cared for this hospital as much as he cared about his own life. He could not let anyone harm the hospital's goodwill.
