Zhang Hao had just returned to his office when he received a phone call from his superior.
"There's an emergency case that needs your attention immediately," the superior said, "but without you, there would be no one on duty in the hospital."
However, the superior couldn't find a better person for the job.
"Just go and come back quickly," the superior instructed, "This patient has always been treated at our hospital."
"They've had a bit of an emergency today; you just need to go over and help with an IV."
Zhang Hao was half-convinced and checked the patient's medical history, sensing that something was strange.
Still, he followed the superior's order, grabbed the medicine and basic equipment, and went to the emergency department.
After a brief discussion with the ambulance driver, they headed to the patient's home for treatment.
Upon arriving, they discovered it was the finest residential complex in the city center.
