“The great river flows east...” In the middle of my dream, I was woken up by the sound of my alarm. I knew it was already 7 a.m. Morning self-study started at 7:40, but luckily, I just had to wait at the entrance of our neighborhood to catch the No. 2 bus to Linhai No. 1 High School, which left at 7:20.
I turned off the alarm, got up, put on my clothes, and headed to the bathroom. Passing by the staircase leading to the second floor, everything was still quiet upstairs. It seemed my parents were still asleep. Unless there was something urgent, they usually woke up around 8 a.m. to go to work.
After washing up, I quickly grabbed my backpack and headed toward the neighborhood entrance.
The number two bus pulled into the neighborhood bus stop exactly at 7:20. After a little over ten minutes, I arrived at the school gate, bought two steamed buns and a cup of soy milk, and headed into the campus.
“Zihan,” I heard someone call from behind as I walked along the rubberized track. I turned around and saw Li Xiaojun. Today, she was wearing her school uniform, her hair tied up in a neat ponytail that revealed her youthful face. The blue-and-white school uniform subtly accentuated her chest, and beneath her long legs clad in blue school trousers, she wore a pair of white canvas shoes.
“She looks so pure today,” I thought. Even though I had seen her many times before, I still found Li Xiaojun quite pleasing to look at.
“Hey, good morning, Xiaojun,” I said, standing still and smiling at her.
“Morning, let’s go,” Li Xiaojun said cheerfully as she walked up to me.
“You said the exchange student is coming to our class soon?” I asked.
“Yeah, last night, Teacher Zhang said she would bring the exchange student to our class during the morning break. She asked me to arrange a warm welcome from the class,” Li Xiaojun replied.
“Alright, is it a Black person or a White person? A boy or a girl?” I asked with interest.
“Guess, hahaha,” Li Xiaojun glanced at me and laughed.
“I won’t guess. If you won’t tell me, I’ll find out soon enough,” I rolled my eyes at her. Li Xiaojun always loved keeping things mysterious.
“Zihan, don’t be impatient. I’ll leave a little suspense for you, hehehe.”
After that, the two of us walked up the stairs to the third floor and entered the classroom.
It seemed like the classmates already knew about the exchange student’s arrival, as the classroom was buzzing with excitement. After finishing my breakfast, I tuned out the noise and started my morning self-study session.
After the morning break, we returned to the classroom but didn’t see any so-called exchange student. For a while, the class thought it was just a rumor.
“Zihan, Teacher Zhang and the principal are bringing the exchange student over,” Li Xiaojun rushed in from outside and said to me, who was sitting in the front row.
“Oh?” My interest was piqued.
“Everyone, quiet! Teacher Zhang and the principal are bringing the exchange student to our class. Let’s give them a warm welcome later, and try to greet them in English,” said Li Xiaojun, standing at the podium as the class monitor.
“OK, sure, no problem, I love you, pretty girl!”
The classmates, who usually didn’t speak much English, suddenly started spouting English phrases.
I couldn’t help but laugh. They didn’t even know if it was a boy or a girl, and they were already saying “I love you”?
“Alright, everyone, quiet. They’re coming soon,” Li Xiaojun said before returning to her seat behind me.
Not long after, we heard the sound of many footsteps approaching from the hallway outside the classroom. “Principal, please, yes, yes, yes,” voices kept coming through. We all fell silent, staring intently at the door. Suddenly, Zhang Min walked in first, followed by a dark-skinned Black male student. He was wearing a long white shirt, gray trousers, and a pair of polished black leather shoes. He didn’t look as muscular as the Black basketball players you see on TV in the NBA, but he seemed stronger than me and a bit taller too.
His short, curly hair was cut into a buzz cut, with thick, dark eyebrows and large eyes. Compared to Asians and Caucasians, he had the typical broad, flat nose and wide mouth of a Black person, with two thick, pale lips underneath. The only white parts of this Black student were the lenses in his big eyes and the teeth and two plump, pink lips revealed when he grinned. Despite his dark skin, he gave off a playful and approachable vibe.
“Huh ... Pfft, hahaha... ‘I love you’? Hahaha...” I seemed to hear a few boys in the back seats snickering and unable to hold back their laughter.
“Class, this student is Sam from South Africa. As an exchange student, Sam will be studying, living, and playing with all of you for the next year. Let’s give him a warm welcome!”
Zhang Min stood at the podium and began to clap, and we all joined in. Sam scratched his head sheepishly, then walked back to the front of the class, looking at us with his big eyes wide open. “My name is Sam, and I’m from Cape Town, South Africa. My Mandarin ... isn’t very good. I hope you can all help me in the future. I love China, I love you all, thank you.”
Sam grew bolder, spreading his arms in an embrace. “Woo-hoo ... OK, no problem, no problem,” the boys in the back row started whistling. “Hahaha, our classmates are quite enthusiastic, and Sam’s self-introduction was brilliant. I hope everyone will take good care of Sam from now on, befriend him, and get along well with this international student. Alright, Teacher Zhang, I won’t say more.”
After the principal said a few words on stage, the female secretary beside him snapped photos frantically. Then, the principal nodded to the teachers and students and walked out of the classroom.
Once the group of teachers followed the principal out, homeroom teacher Zhang Min returned to the podium and looked at us. “Hehehe, students, starting today, Sam is one of us. To help Sam quickly integrate into our Class 12 family, we’ll rearrange the seating now. Two students per row. Sam will sit with our class monitor, Wang Zihan. Zihan, make sure to communicate more with Sam from now on. This is a rare opportunity,” Zhang Min said, giving me a meaningful look. Damn, they’re pairing Sam with me? Are they out of their minds?!
“Alright, Teacher Zhang,” I replied. But what could I do? I was the class monitor, after all.
I forced a smile and looked at Sam on the podium. Sam didn’t hold back either, walking toward me with a smooth, outstretched hand, his lips spread wide as he grinned at me. “Oh, so you’re the class monitor, Wang Zihan? I heard from the teachers before I came that you’re an excellent student. From now on, we’ll be good friends, Zihan,” Sam said without any reservation, enthusiastically trying to hug me. “Uh, Sam, no big deal, no big deal,” I shook his hand and then endured his enthusiastic hug. Are all Africans this warm and open?!
I’d heard that Black people have a certain smell, but I didn’t notice any unpleasant odor on Sam.
And so, Sam from Cape Town sat with me in class. At noon, we held a welcome ceremony for him in the classroom. Under the homeroom teacher’s instructions, class monitor Li Xiaojun bought plenty of snacks and food. Everyone happily chatted and interacted with Sam, who didn’t shy away from sharing everything, including stories about his life in South Africa. With Sam’s exaggerated expressions and gestures, he had everyone roaring with laughter.
It wasn’t until the afternoon, just before school ended, that homeroom teacher Zhang Min called me to her office.
“Zihan, how do you feel about being with Sam?” Zhang Min smiled as she looked at me. “It’s fine. Sam is very outgoing, and we had a great time,” I said. Sam was easy to get along with and told me many funny stories about his life in South Africa. He even mentioned having a girlfriend back there and how they had tearfully parted ways when he came to China as an exchange student. Sam’s exaggerated gestures and naturally comical appearance made me laugh uncontrollably.
“Well, that’s good. Make sure to communicate well with him—it’s a rare opportunity,” Zhang Min said, taking a sip of tea from the cup on the table. “There’s another matter. Since Sam is new here, to help exchange students better experience and integrate into the Chinese learning and living environment, the school has decided to arrange for Sam to stay with a local student’s family. Of course, the city will provide some subsidies. After careful consideration, we’ve decided to have Sam stay at your home and live and study with you. As you know, given your entrance exam results, the school plans to support you in applying to universities abroad and striving to study overseas.”
Zhang Min smiled at me. “This...” I understood the school’s intention. My tuition at Linhai No. 1 High School was fully waived, and I had even received a 5,000-yuan reward.
But having Sam stay at my home—I didn’t object, but my parents might not be so sure.
“I know what you’re worried about. We’ve already called your parents to inform and explain the situation to them, and they’re very welcoming. Now, we just need to know how you feel about it.”
Zhang Min looked at me gently. After all, I was her treasure.
“If my parents agree, then it’s fine. Getting along with him has been good so far,” I said, looking at Zhang Min.
“Good. After school today, relevant officials from the city’s education commission will take Sam to your home. You two can head back together once classes are over,” Zhang Min patted my shoulder.
“This ... isn’t it a bit too sudden?” I asked.
“Not at all. The sooner you get to know each other, the better it’ll be for your future interactions. Don’t worry. Sam’s family has a large business in South Africa, so his manners are nothing to worry about. Just communicate well with him—it’ll definitely benefit you,” Zhang Min said with a smile.
“Alright,” I nodded. Since Zhang Min put it that way, maybe getting along well with Sam would help me climb the ladder of success in the future.
Back in the classroom, Sam smiled at me. “Zihan, where did you go?”
“To the teacher’s office. We’ll walk home together after school,” I said.
“Oh, good, my Zihan,” Sam spread his arms open again, making me feel awkward.
“Zihan, Sam,” Li Xiaojun called out from behind us.
“Oh, beautiful class monitor,” Sam said upon seeing Li Xiaojun. I could sense his eyes widening and brightening.
“Giggle, Sam, you don’t need to be so formal in China,” Li Xiaojun covered her mouth and laughed.
“How could I not? The class monitor is one of the most beautiful girls I’ve ever seen. I mean it from the bottom of my heart,” Sam said, extending his hand as if to shake hers.
“Giggle,” Li Xiaojun had no choice but to reach out and shake his hand.
“I heard from Teacher Zhang that Sam will be staying at your home, right?” Li Xiaojun looked at me.
“Yeah, I just found out too,” I pursed my lips.
“Oh, really, Zihan? Then we’ll be as close as sharing the same pants from now on!” Sam happily hugged me again.
“Uh, yeah, sure,” I thought to myself. This Sam really doesn’t know about boundaries between guys, does he?
