Early morning.
Ling Ran had a long and good sleep. He only woke up at six o'clock.
He got out of the bed and washed up. When he opened the door to the courtyard, he saw that someone was already waiting outside the door.
"Old Man Liu? Why didn't you knock on the door?" Ling Ran was surprised. Since his family ran a clinic, they would inevitably encounter patients who needed emergency treatment. This was especially true some time ago when it was not so convenient to go to the hospital's Emergency Department. It was very normal for people to knock on the door in the middle of the night to seek treatment. Those with senior citizens or young children at home were Lower Groove Clinic's frequenters.
