Chapter 127: Dad, I really understand better than you

Xu Shouyun and Wang Xiaping actually only stayed in Kyoto for two days. They would fly to Nanjing on Monday morning for a two-person world, then to Hangzhou, and finally return to Rongcheng from Hangzhou.

7 days of annual leave, arranged fully.

After eating, walked around casually outside, and finalized tomorrow's itinerary, it was already past 9 PM.

A group of people took a taxi to the hotel where Xu Shouyun and his wife were staying. From the hotel to Jingda, it was only a 20-plus minute walk.

"Dad, Mom, leaving."

"Uncle, Auntie, goodbye."

Wang Xiaping said with a smile: "Alright, walk slowly on the road, pay attention to safety."

Sunday morning 6:00, Xu Qingzhou packed up cleanly and went to find Old Xu and his wife with Song Yao.

Read! {

This is the first time Xu Qingzhou has come here since his rebirth. Listening to the loud national anthem and watching the red flag of the flag-raising, a kind of emotion often emerges in his heart.

"Mm, it's his parents."

"Xu Qingzhou!"

"We are just friends." Xu Qingzhou denied. So far, they are clear and white, okay? Dating means being managed, can it be as interesting as doing research?

Seeing Zhang Qiong: "..."

!.

"I'm carrying things!"

After eating, everyone went to Nanluoguxiang nearby.

Xu Shouyun saw Wang Xiaping and the others still needed a while, asked: "Are you and Little Yao dating?"

Arrived at around 7:30 AM for the flag-raising, and there was a sea of people when they arrived. 【127-20

Song Yao wore the pink gloves Xu Qingzhou had given her, covered her ears, and nodded in admission, "A little."

When their own children are dating, what parents worry about is nothing more than whether the two are a good match.

In the afternoon, when they arrived at the Small Stone Tablet Alley next to Shichahai, the four of them had already split into two groups. Xu Qingzhou and Old Xu were lagging behind; Xu Qingzhou was holding Song Yao's down jacket, and Old Xu was holding his wife's cashmere coat.

Such a good girl... there must be many people pursuing her.

Watching Old Xu and his mother enter the security checkpoint, Xu Qingzhou also turned and left. He spent several dozen yuan of his hard-earned money at the airport entrance to take a taxi back to school, sinking into complex and difficult calculations.

The boys were completely defeated. Up ahead, the two women were attracted by the dazzling array of goods, discussing which one to buy.

"You must be tired today, right?" Xu Qingzhou asked with a smile, having chatted with his mother the whole way.

After watching the flag-raising, the next step was to accompany Xu Shouyun and Wang Xiaping shopping.

"But those are Xu Qingzhou's parents!"

Walking a bit further away, Song Yao clutched her chest and let out a breath. Even though they were just playing all day, it felt more tiring than her usual day of reading books.

"Dad, can we not bring these things up?" Xu Qingzhou said with a dark face. If they kept talking, they'd get to the topic of condoms, but they really didn't have anything going on right now!

Xu Qingzhou was carrying a large pile of things; some were given by Song Shisong and the others, and some were brought by Old Xu and his wife. Added together, they were two large bags, specifically left for Xu Qingzhou to carry.

Xu Qingzhou and the other man sat on a chair outside.

The computer was running the PN model, rapidly generating prime numbers and processing them.

Under the streetlights, the figures of the two young people drifted further away, walking slowly toward Jingda.

Sunday passed just like that. "."

So Xu Qingzhou took the four of them to find a restaurant near Nanluoguxiang.

At 4:00 PM, under Xu Qingzhou's strong insistence and Old Xu's seconding, Wang Xiaping and Song Yao, who were having a great time shopping, finally agreed to go eat first.

As he spoke, Old Xu glanced at the two people in the shop picking out hats: "Your mom really likes Xiao Yao; she hasn't stopped smiling these past two days. To be honest, I also think Xiao Yao is great, but I'm different from your mom; I don't think you two must be a certain way. After all, feelings are something you have to handle yourselves."

"No," Song Yao shook her head.

"."

"Dad," Xu Qingzhou said seriously, "I really understand these things better than you."

"But looking at them, it doesn't seem like that kind of relationship."

"I have to say, this is the real business, you guys..."

December 22nd.

Xu Shouyun smiled and shook his head, "They say times are progressing, so why are you young people not as bold as us? If you like someone, go pursue them; don't use friends as an excuse."

As soon as Song Yao walked in carrying the things, Seeing Zhang Qiong asked impatiently, "Xiao Yao, have you and Xu Qingzhou already reached the stage of meeting the parents?"

If one really had to mention looks... Old Xu often felt a sense of unreality—could the pig he raised really have managed to root up such a good cabbage? Thinking to himself, Old Xu thought of something more important, his expression tightened, and he said, "However... you are both adults now; you should understand what you need to understand, you must be careful..."

When Song Yao returned to the dormitory, only Seeing Zhang Qiong was there.

"You're so gentle today, I'm really not used to it."

As night fell, Nanluoguxiang became even livelier. Lanterns emitted orange light, people came and went, prosperity was fully displayed, and one could feel the unique Beijing atmosphere.

Not until the two figures disappeared around the street corner did the couple return to the hotel.

Song Yao, the daughter of the Old Song family, there's no need to mention her family background; everyone knows the roots. Her personality is also good, gentle and soft. Both are from the same school, so their values and knowledge naturally align.

Xu Shouyun glanced at the two backs in the distance; at this moment, he also felt a bit dazed. It felt like his son, from an innocent teenager, had suddenly become a mature young man.

Whether they are a good match is multifaceted, such as personality, values, and family background; in his view, looks are secondary.

The next day, Song Yao had class in the morning, so Xu Qingzhou was the only one to send Xu Shouyun and Wang Xiaping to the airport, letting them start their 5-day sweet trip for two.

The workstation at the Supercomputing Center.

Plans couldn't keep up with changes; until 3:30 PM, the group was still at Dazang Longhua Temple in Shichahai, so they couldn't go to the Temple of Heaven.

At the hotel entrance, Wang Xiaping muttered, "Old Xu, don't you think this scene looks a lot like sending off a son and daughter-in-law?"

Xu Qingzhou and Song Yao were here for the second time, but since Wang Xiaping and the others were there this time, especially since it was night, the experience in this commercial street with Kyoto characteristics was still very good.

【defplot_prime_gaps(n_max): primes=generate_primes_until(n_max)el(「log^2(p_n)「)n_max=1000000000000#plot_prime_gaps(n_max)】

"Dating, dating, don't you become boyfriend and girlfriend after dating for a while?" Wang Xiaping felt there was no problem. However, after Xu Shouyun said that, she really got a bit anxious: "Ask your son tomorrow what he's actually thinking."

"Yeah, I'll ask tomorrow."

Up ahead, Wang Xiaping and Song Yao were walking arm in arm.

"len(primes)<2, if I substitute it into the calculation..."

Xu Qingzhou took a deep breath and grabbed a sheet of draft paper to calculate.

Ten minutes later, staring fixedly at the calculation on the table, Xu Qingzhou stood up abruptly from his chair, his expression excited: "Calculating like this... (pn+1-pn)/(lnpn)^2=1."

"So, the Cramér conjecture holds true!"
