"You are being unreasonable." Xiang Nan waved his hand and said with a smile, "Have you never heard of that saying, filial piety is the first of all good deeds, and the heart is not concerned with deeds, and there is no filial son in a poor family. There are few perfect people in this world."

"Strong words to make sense." Qiao Yingzi spat.

"Okay, if you really can't afford to lose, then let's bet on something else." Xiang Nan said with a smile.

"Bah, no one can afford to lose." Qiao Yingzi said harshly, "Okay, just bet like this, you can't win anyway."

"Don't be so full of words." Xiang Nan said with a smile, "Don't forget that there is still one thing in a thousand miles."

"Yes, yes, unless the sun comes out from the west." Qiao Yingzi still said stubbornly.

"It's not difficult to see the sun rising from the west. As long as the speed of walking due west exceeds the rotation speed of the earth, you can see the sun rising from the west." Xiang Nan waved his hand and said with a smile.

"Huh!" Seeing that he was still eloquent, Qiao Yingzi gave him another angry look.

…

"By the way, the telescope that Uncle Dong gave you is pretty good." Xiang Nan said when he had nothing to say.

"What do you know?" Qiao Yingzi rolled her eyes and said, still feeling resentful about Xiang Nan's teasing.

"If I don't know anything else, how can this telescope stump me?" Xiang Nan smiled and said, "This is the American Celestron brand 102az telescope. The main mirror has a diameter of 100-200 mm, a main mirror length of 966 mm, and a focal ratio of It’s f/5.9…”

The more Qiao Yingzi listened, the more surprised she became, "How do you know this?"

"Actually, I'm also very interested in astronomy." Xiang Nan said with a smile, "So I read some relevant information."

"Are you also interested in astronomy?! Why haven't I heard you mention it before?" Qiao Yingzi asked in surprise.

"If you don't believe me, you can try it." Xiang Nan said with a smile, "Let's ask each other questions to see who knows better, you or me."

"Hey, you said you're fat and you're out of breath." Seeing Xiang Nan's arrogance, Qiao Yingzi couldn't help but ignite her fighting spirit, "Okay, let me ask you the simplest question first. What is the first speed of the universe? ?”

"7.9km/s." Xiang Nan answered directly without thinking, "It's my turn, and I'll ask you a simple question. You said you like astronomy, but do you know how many categories astronomy is divided into?"

"..." Qiao Yingzi was stunned for a moment, then shook her head.

Her understanding of astronomy is at the level of an enthusiast. She even thought that astronauts majored in astronomy, but in fact astronauts majored in aerospace.

"Let me teach you a lesson. There are many ways to classify astronomy. According to research methods, there are astrometry, celestial mechanics, astrophysics, and astronomical technology and methods.

According to the observation method, it can be divided into optical astronomy, radio astronomy, infrared astronomy and space astronomy.

These categories can be further subdivided. For example, astrophysics can be divided into solar physics, solar system physics, stellar physics, stellar astronomy, planetary physics, galaxy astronomy, cosmology, cosmochemistry, celestial evolution, and radio Astronomy, space astronomy, high-energy astrophysics..." Xiang Nan said with a smile.

"Fang Hou'er, how do you know so much?" Qiao Yingzi was frightened after hearing this and asked in surprise.

"We have been separated for three days, so we should look at each other with admiration." Xiang Nan said with a smile, "I can tell you responsibly that I am no longer the Fang Yifan I was before."

"Smelly fart~" Qiao Yingzi stuck out her tongue.

…

While they were chatting, Fangyuan had already arrived and brought lunch.

Xiang Nan and Qiao Yingzi came out of the room immediately.

"Old Qiao is here, and I just happened to buy roast duck. Let's roast duck and have some beer." When Fangyuan saw Qiao Weidong, he immediately suggested with a smile.

"Okay." Qiao Weidong accepted it readily, "Is there any beer at home?"

"What kind of wine are you drinking? He has already eaten it." Song Qian immediately stopped her after hearing this.

"Have you eaten yet?" Fangyuan was puzzled.

"No, no." Qiao Weidong quickly denied.

"You go ahead and slice the duck first," Tong Wenjie advised Fang Yuan.

Fangyuan hesitated for a moment, then turned and went to the kitchen.

Qiao Weidong couldn't help but sigh when he saw that no one was staying with him anymore, "What? I'll leave first. Anyway, I've already eaten. Fangyuan'er, let's meet at the swearing-in ceremony tomorrow."

"Okay." Fang Yuan responded in the kitchen.

When Qiao Yingzi saw her father being kicked away, she couldn't help but show an unbearable expression.

"Qiao Weidong, wait a minute." After Song Qian heard the conversation between the two, she immediately came out of the kitchen and said coldly, "Come with me and have a chat."

Qiao Weidong had no choice but to enter the bedroom with Song Qian.

"Hey, my dad is going to be annoyed again." Seeing this, Qiao Yingzi shook her head and sighed, "You said that he has been giving me things every now and then in the past three days, and every time he was yelled at by my mother, he ran away. I see

It’s really distressing.”

"You don't understand this. Hitting hurts, scolding means loving, and it's not pleasant if you don't hit or scold." Upon hearing this, Xiang Nan said with a smile, "In my opinion, Uncle Dong must have lingering feelings for Aunt Song."

"Really?!" When Qiao Yingzi heard this, her eyes suddenly lit up, and then she questioned, "Stop talking nonsense, my dad has a girlfriend, and they have been together for three years, how can he still have feelings for my mom?

Already?"

"Use your little head and think about it carefully. Your dad is not a masochist. If he just wants to give you something, then he can just send it to school without getting married. Why bother getting scolded every time he brings something to your door?"

Xiang Nan smiled and analyzed, "It can be seen that he thinks you are fake, but he thinks your mother is real."

Hearing what he said, Qiao Yingzi suddenly became energetic.

"Besides, your dad is not young anymore, and neither is his girlfriend. They have been together for three years, and their relationship should be very deep.

If your father didn't have his heart set on him, how could he have been in a relationship for so long without getting married? He's not a young man in his twenties and has a lot of time to waste." Xiang Nan analyzed again.

"Fang Hou'er, are everything you said true or false?" Qiao Yingzi looked at Xiang Nan in surprise.

She hoped that what Xiang Nan said was true, but she couldn't believe it was true.

To be honest, she had always hoped that her father and mother could get back together. In this way, their family could be together again, reunited and harmonious.

"Why are you so stupid?" Xiang Nan said with a smile, "If it's true or false, you can verify it and you'll be done with it.

Later, when you find a chance to tell your dad, just say that your mom is sick, has a cold, has a high fever, or has diarrhea. You will know if your dad comes to the house in a hurry."

"Fang Hou'er, you are such a monkey. You can actually come up with such an idea." Qiao Yingzi couldn't help but be surprised after hearing this.

Xiang Nan smiled.
