He Li ran home and quickly ran to Hezhi's room, at this time He Li was panting, "Sister.... Sister, I... Here it comes. But Hezhi didn't squeak and looked at the newspaper she was holding. Heli stepped forward and waved his hand in front of her, but Hezhi was still looking at the paper.

"Sister!

He Li patted He Zhi on the shoulder, and then He Zhi reacted, she looked at He Li, and her eyes were a little dim

"Sister, show me what you have in your hand." Hurley said, picking up the newspaper.

Hezhi said: "I don't know what's going on, how can this be? It's impossible! Absolutely impossible!" Heli looked at the headline of the newspaper, which read:

"Modern natural mathematics toppers, why is the truth so sensational in Shanghai?"

"The true ancestor Chongzhi's descendant Hezhi', who alone has the magic of mathematics."

He Li flipped through a lot of newspapers, looked at a lot of headlines that were like this, and the newspaper also inserted a photo of Heli and Hezhi in Heli's pencil case, Heli panicked, he was suspicious one second, and he believed it the next. "This... Is this true?" Heli's hands began to tremble, Hezhi began to shed tears, she said: "We can't stay here anymore, or we will suffer, let's go out for a while, Heli, go!" After speaking, she hurriedly took her schoolbag and brought her study materials. Heli also put his schoolbag in order, walked to his room and looked at the photo of him and Hezhi, he thought, "To bring it or not to bring it?" He thought for a long time, and Hezhi began to call him: "Heli, are you alright?" Heli could only take his schoolbag with him, "Let's not take the group photo." So they started on their way.

Shanghai Hongkou Hengbang Bridge

Heli and Hezhi got on the No. 18 bus and were about to go to People's Square, but they were stunned when they just got on the bus, and the bus driver suddenly asked Hezhi: "This young lady, can you help calculate how far the Nanpu Bridge Guard's Barracks Road is from here?" Thank you!" Hezhi was a little confused, why did the bus driver ask her the distance to the terminal? But she had no choice but to help him calculate, otherwise the driver would not drive, "There are still 5.9 kilometers left." ”

"Thank you." The driver closed the door and drove off. Hezhi Heli walked to the back of the carriage, but encountered another problem, a male student who was about to enter the third year of high school asked Hezhi a question: "Well, sister, look at this picture, in the triangle ABC, a=5, b=3, c=120, then sinA: what is the value of sinB?"

Hezhi thought, "Why is there still someone asking me a question?" Forget it. So she told him the answer ideas step by step.

But it's not just the sophomore who asks her questions, almost everyone on the bus asks her questions about math...

"Sister, how do you calculate the area of the circle?"

"Miss, I have to pay taxes in a few days, and I won't calculate how much tax I have to pay, please help me calculate thank you."

At this time, Heli was in a hurry, the whole bus became noisy, and at this time the bus stopped at Qufu Road, Heli held Hezhi's hand, and quickly pulled Hezhi off the bus, but someone chased them, "Wait, you haven't answered my question yet!" Hey!" Some people also got off the bus and chased them privately, but at this time, Hezhi couldn't escape, and someone blocked their way, with evil eyes: "Tell me!" The circumference of the rectangle!" At this time, Hezhi was helpless, so he could only obediently tell them the answer ideas.
