The back-row chair always saved for the classmate in hospital

In the classroom of Class 3, second year of junior high, the window seat in the last row has "seated two people" for over a year: one is Lin Xiaoman, who comes to school, and the other is the empty chair beside her.

The chair is Xiaoman's. She fell ill and took a leave from school. It was never moved away, because the homeroom teacher, Mr. Chen, gave the order: "Don't touch it. That's Xiaoman's place."

Xiaoman has a chronic illness and has been hospitalized again and again. Since the second semester of seventh grade, she has spent less than a month in the classroom per term. By the school's enrollment rules she applied for a leave of absence, and with her coursework slipping, repeating the year after recovery would have been perfectly normal. But Mr. Chen refused to let her schooling "wait until she's better."

He made a decision that looked like a burden at the time: every Wednesday and Friday after school, he recorded the week's two main subjects on his phone and sent her the videos; for every unit he printed the lecture notes and had the class monitor carry them over; on the days she could come to school, he caught her up one-on-one. A colleague advised him: "Students on leave get makeup classes when they return — that's the rule. What you're doing is volunteering for extra work." Mr. Chen scratched his head: "Fall behind in lessons, and it's easy to catch up. Fall behind in your heart, and it's hard to pull back. Keep her chair for her, and she keeps a seat in her heart."

The most moving part was the children. They drew up a duty roster on their own: each group took turns copying the day's class notes, adding a line of "today's big news," and handing them to Mr. Chen after school to mail. The notes grew thicker and thicker, turning from pure coursework into a chronicle: a record broken at the sports meet, the blackboard bulletin winning first place, the cat by the school gate having kittens... Lin Xiaoman says that on the hardest nights of chemotherapy in the hospital, she read that stack of notebooks over and over. "Reading them, I didn't feel like I was sick. It felt like being at school."

Once, during a video call, Mr. Chen remarked offhandedly that everything in class was as usual, and Xiaoman asked quietly from her end of the screen: "Is my chair still there?" There was a beat of silence on the classroom side; then the class monitor turned the camera toward the back row — the chair stood clean in its place, with a cushion on its back that the class had chipped in to buy. At the far end of the call, Xiaoman cried.

An empty chair, left standing there, is a sentence being said all day long: we haven't crossed your name off. Come back whenever you like — the lessons are here, the friends are here, your place is here.

When her condition stabilized, Xiaoman returned to school — no repeating the year. The day she sat back down in that chair, the whole class applauded, and Mr. Chen set something on her desk: the seventy-eight sets of notes the class had mailed her over a year and a half, arranged in date order and bound into a volume, the cover reading — "Xiaoman's seat was never gone."

Today Lin Xiaoman ranks in the upper-middle of her class, laughs easily, and has joined the school choir. Her mother says one habit from her sick days has never changed: every Friday after school she stays behind to wipe down her own desk and chair, then helps the student on duty wipe the back-row chair and its cushion too.

"That's my place," she says. "It has to be me who wipes it."

The year that class graduated, the school made a short film of the story. It ends with a line from Mr. Chen that left many viewers' eyes burning: "I've taught for thirty years, and I'm more and more certain of one thing: a teacher's podium isn't at the front of the room. It's wherever a student needs it."
