In front of him, Wencheng said, "the sun and the moon are shining, and the sun and the moon are shining? It seems that you know a lot about astrology, too! "

Xia Yuanqiu shook his head: "it's just that I know something. Compared with you, who can measure the star power all day long, it's too far away."

At this time, Wencheng had completely forgotten his previous judgment of Xia Yuanqiu, and with a face full of interest, he asked Xia Yuanqiu, "so, do you believe that the number of seasons can be measured by star watching?"

Xia Yuanqiu nodded naturally: "it's not to believe, it's to be sure that the stars are right in time and season. There's no need to doubt it!"

Wencheng's body excited to stand up, finally, he finally found a willing to believe his argument for many years.

Wencheng's voice trembled slightly: "tell me, what's your opinion on how many seasons to observe the stars?"

Opinions? Xia Yuanqiu didn't know much about astrology, but when she was studying in the 21st century, she was involved in this area. Although she didn't know much about it, she thought that it should be enough to fool this guy in front of her.

Xia Yuanqiu cleared his throat and searched his brain for the passage from the book: "doubing East refers to spring in the world, doubing South refers to summer in the world, doubing West refers to autumn in the world, doubing North refers to winter in the world."

Wencheng asked: "when you talk about doubing, do you mean seven stars in the sky like doubing?"

Xia Yuanqiu nodded: "it's the Big Dipper. We can judge the season by observing the position of the Big Dipper at dusk, and this kind of observing the regular changes of the sky to determine the four seasons is called" observing the images and timing. "

" observing the images and timing, that's right. It's very appropriate to describe it as observing the images and timing. " Wen Cheng was excited to rummage on the table. He found a piece of paper with many pictures of the Big Dipper. At the bottom of each picture, there were lines of notes, which said the climate change and the sun at that time.

It seems that Wencheng has measured the position change of the big dipper and the change of the four seasons.

Yun xiangtian is at a loss, but seeing Wencheng's appearance, he thinks that Xia Yuanqiu really understands the astronomical phenomena, not pretends to understand them, but he can't understand them himself.

He walked forward with a smile and said, "how about it? Is Yuanqiu the brainless girl you imagine

Wencheng quickly waved: "if she has no brain, then I am brain disabled!"

Wen Cheng said, "what else can I do for a smart and celestial being like you?"

Xia Yuanqiu said with a smile: "although I know a little about astronomical phenomena, I don't observe stars day and night like you, so I need to trouble you to help me with some things."

Wencheng said: "you say, as long as I know Wencheng, I will not hide!"

In the Xia, yuan and autumn dynasties, Wen Cheng bowed his hand: "thank you, brother Wen!" She turned around, looked up at the bright sun in the sky and said, "I wonder if brother Wen has ever heard of an eclipse?"

Wencheng's face slightly changed, and he asked: "you said the eclipse, but the day is dark, and there is no light day?"

Xia Yuanqiu said: "yes, it's just day and night, and there is no light. Brother Wen knows?"

Wen Cheng nodded: "I've seen three eclipses in total. It's like the sky collapses and there's no day in the dark. It's like a ghost attacking the city."

"Do you know when the next eclipse will be?" Xia Yuanqiu asked again.

Wen Cheng said: "the first time I saw a solar eclipse was when I was ten years old. It was the beginning of that year that I fell in love with the astronomical phenomena. The second solar eclipse was when I was seventeen years old. In that year, I made great achievements in learning star watching. The third solar eclipse was when I was twenty-four years old. In that year, my mother left me forever!"
