Wang Yi hurriedly walked to the door and turned around a few more times, lest he forget something.

She sends him out, watches him disappear at the end of the hallway, and then returns to the house and opens the window to release the air that has been building up for days. She sat in the only chair and opened the photo, scrolling through it, and there were photos of him just arriving in Berlin, in front of Big Ben, as well as a night view of the Tower of London and a stall in front of the Baker Street Museum. She began to miss the city she had just passed through two weeks earlier, and it contained almost all of her vision of a European city, except that she had to drive on the left.

She looked at it with eagerness, trying to dig out familiar corners in the photo. However, after some ordinary street scene photos, she actually saw a group photo of Wang Yi and Ye Feng, the two of them were standing in the sun, and behind them was a three-story ordinary house.

"Hungry, huh? There's a nice Italian restaurant nearby, why don't you try it? Wang Yi didn't know when he had come back, standing at the door and locking the door while saying, "How about cooking and eating at night?" ”

She nodded, quickly turned off her computer, and followed him out the door, walking down the clean streets of Berlin. Green street signs are erected at each intersection, and street names are clearly marked. It's a city that makes it hard to get lost, and the old buildings lost during the Second World War have been replaced by new ones, and the sculptures near the Brandenburg Gate have remained original compared to the swarthy sculptures of Prague. The red elevated subway runs between the glass-walled office buildings. Unlike Amsterdam, the city centre is a zoo. The design reminds Chen Ying of a time when she was a child, when her parents took her to the center of her city on a weekend, where there is a square and a zoo next to it.

"I'm one of the few Asian students at this university." As they waited in line in front of the restaurant, Mr. Wang said, "There were two other Japanese and one Korean-American. This made me feel even more lonely when I first arrived. I have tried to write to you several times, but the fact that you may be in a similar situation in Denmark to mine does not want to burden you any more. This is probably not the original purpose of international exchange, and each of us should learn to bear our loneliness. ”

"I received your flowers, they are beautiful." She said.

"Yes, growing flowers has become a part of my life now, like my fingers. In China I hate the hustle and bustle and always avoid the crowds. Now I'm abandoned by the crowd and have a lot of time left alone every day – I spend that time researching European culture, randomly picking a few books from the library to read. ”

"I was forced to exercise and often went for walks in the wilderness."

"Does it work?"

"It's okay."

Wang Yi laughed so much that tears flowed out, and Chen Ying also laughed. The waiter beckoned them in and led them to a small table by the window.

"The pizza here was delicious. I'll do some, can I? Wang Yi asked as he flipped through the menu.

"It's all up to you."

"Students in China still think that we are happy here." When the pizza was served, Wang Yi said, "Even though it's an English program, I always provide German reference books, and I don't know how I survived." I've met a few international students on the road who have been ventilating all day long to give out free communion and spending the night at McDonald's or train stations. They were probably dropped out of school, and they were too embarrassed to return to China, so they have been stuck here. ”

"Also a student at Humboldt University?"

"I don't know. They met twice and never contacted each other again. I later changed dorms once because I wanted to stay in a room with a north-facing window. ”

He was silent as he spoke, munching on the pizza in front of him. Tasting Italian food in Germany is nothing new, and they sit facing each other and swallow the exoticism. Humboldt University is separated from the street by a black fence more than one person high, and marble statues of the founder's brothers are placed on the pillars at the main entrance. Many tourists stopped to watch and take pictures outside the fence.

"I appreciate the University of Copenhagen more in this regard." Chen Ying looked at the entrance of the university and said, "Maybe it doesn't have the grandeur and solemnity of the school here, but whoever is willing to walk along the street can enter the university." ”
