After the tour of the museum, Chen Ying hurried back to the hotel. She pushed the packed suitcase into the luggage compartment at the bottom of the coach. After counting the number of people, they hurriedly set off, and Wang Yi stood on the side of the street to watch her leave.

"Who's that? Is your boyfriend? The Vietnamese girl pointed to Wang Yi and asked.

Chen Ying smiled and shook her head.

"You're a handsome boy." A Greek girl also leaned over to look at the window, waving at him as she watched.

Chen Ying blushed and looked out the window on the other side. The bus speeds past the gates of the London School of Economics and Political Science, past the Cleopatra Obelisk and Southwark Cathedral, and finally to the British Library. The lead teacher drove the students into St Pancras International Railway Station like a herd of sheep, and then they sat on their suitcases with their tickets and waited. The school has chartered two carriages, and all they have to do is carry their suitcases and find empty seats. The teacher counted the number of people repeatedly and advised them not to go to the bathroom before the train started.

"It's inhuman!" A burly American boy stood up and shouted. The Portuguese boy next to him hurriedly pulled him back into his seat.

The Eurostar is impeccable as an international means of transport, but it is not a satisfying experience for passengers who want to feast their eyes, especially if they are hungry. Tired of seeing the gray-black walls around her, Chen Ying wanted to open the computer to check the Internet for new emails, but the eardrums on both sides were uncomfortably swollen due to air pressure. She took a few deep breaths to no avail. The pain grew more intense as time went on, and she didn't bother to do anything else, but turned her head to yawn against the glass window.

"It's better to yawn with your nose pinched." Said a Japanese girl sitting next to her. She also gave a demonstration.

"Thank you." Chen Ying said gratefully. She tried to make her ears more comfortable as she had just learned.

"After the tour in Belgium, we will disband. Planning where to travel? The Japanese girl continued.

"Probably going to the Netherlands." She said casually. However, things are not as easy as she said, she originally only looked at the map and planned at random, and she had no clue how to implement the specific itinerary, not to mention that the two Chinese girls who came with her had already booked tickets to Italy. She will face a journey alone.

"Nice Holland. There are patches of tulips, windmills, and it's the only country in Europe where marijuana is allowed. The Japanese girl continued, "I still go to France – I want to see the Louvre and Notre Dame Cathedral, and the Champs-Élysées ......."

Chen Ying didn't listen to what the Japanese girl said later. She had in her mind the plain black-painted doors of Baker Street in the morning, the creaky staircase for only one person to go up and down, the white enamel washbasin and towel rack made of wire, and the dusted glass instruments on the old wooden table covered with scars. Some of the instruments she had seen in Ms. Liang's lab were much older, with rubber stoppers on the top of the bottles hardening with age. She remembered that from the window on the second floor of the house, she could see the red public phone booth not far from the corner of the street, which was connected like a slot machine eating a coin, and then hung up without saying a few words. She remembers Wang Yi telling her that he would go to the Netherlands on his way back to Germany in a few days, and asked her if she would like to go with him to see Van Gogh's exhibition.

But she was going to go alone, not wanting to be with him again. When they met in England, he always looked at her politely, which made her confused and guilty. She wanted to get out of this situation, and she wanted to wander around in other strange lands alone, even if it was a wandering, as long as she had access to the Internet and a phone line.

The Netherlands borders Belgium, so it's nice to go straight there. She would then turn south, from France to Austria or the Czech Republic. In short, she was going to go around Germany, away from his world, and go around in circles to return to Denmark. She couldn't figure out why she suddenly wanted to avoid him, but she remembered him talking about plans to go to The Hague for his birthday, one day in early November.

"You can go and see the International Tribunal." She looked at the map of the Netherlands and thought. She had heard that it was just a quiet town, but there were many things that had happened that affected the world. Isn't life like this? Beneath the calm lies the wind and waves.

The train was speeding through the dark tunnel, and Chen Ying looked at her face reflected in the glass window. When she called this morning, she knew that Qin Hong was sick, kidney stones had tormented him for several days, and last night she was so painful that she couldn't stand it and went to the hospital to hang up for an emergency. The operation has been scheduled, and the torturous stones will be broken today. He lay in the hospital, forced to drink a lot of water. She would rather he not reply to her messages for some other reason than to hear such disturbing news. Far away, she couldn't do anything, only sent him some money from the Internet, so that he could recuperate with peace of mind.

She actually wanted to go back and spend this time with him. She could imagine him lying alone in the hospital, his pale face distorted by the pain. She felt guilty that she couldn't be around him, and she wanted him to get healthy and go to see the long-awaited impressionist paintings together. About a year ago today, they visited the museum's exhibitions together. She began to thank him for his usual friendliness, Ji Na had visited him, and the roommate Chen Ying had never met, who had carried Qin Hong into the nearby hospital late at night.

"No day is peaceful except in our hearts." Chen Ying read the pamphlets handed out, which were full of Maeterlinck's introductions, and after the afternoon tour, they would go to see the writer's representative play, "The Blue Bird", in the evening. Chen Ying was worried about Qin Hong's affairs in her heart, and she was silent all the way, thinking like water overflowing from her heart in a pond after a rain. She couldn't bear to let the intense worry creep up her brow. The students in the first two rows were happily playing Texas Hold'em, and after a while, the three of them were out.
