Mr. Dong Guo

The old professor smiled brightly, and seemed to be more interested in teaching Guo Xiaobei's math problems than in teaching college students professional courses.

After a class was over, Guo Xiaobei thanked the old professor sincerely, and Guo Qiyu also stood up and bowed to thank him.

The old professor stood up, "My grandson is about the same age, but he is definitely not as smart as Xiao Bei, nor is he as diligent and inquisitive as Xiao Bei."

"Thank you." Guo Qiyu said, as if he was praising himself, his ears turned red.

The old professor thought for a while and asked, "Which elementary school is Xiaobei studying in now? Why do you follow you to class all day?"

Guo Qiyu was taken aback, hesitated for a moment, and mumbled: "Because of many reasons, Xiaobei does not have a registered permanent residence and cannot go to school. These are all things he taught himself."

"Self-study?"

The old professor was even more surprised, deliberately ignoring the reason why the child did not have a registered permanent residence, and praised repeatedly, "Xiao Bei is an incredible child!"

He added: "Anyway, Xiaobei doesn't go to school, why not come to my house to study with my grandson during the summer vacation."

Guo Qiyu was taken aback.

"It's embarrassing to say that my grandson is really hard to learn, but he is very competitive. If Xiaobei is around, he will definitely rush to learn. This is a last resort."

"This is too much trouble for you." Guo Qiyu said in a daze.

"No trouble, Xiaobei is very good!" said the old professor, "I will have lunch at my house. Speaking of which, Xiaobei is still troublesome."

Guo Qiyu's eyes turned red, he didn't expect the old professor to be so reasonable and understanding.

"Xiaobei, what do you think?" He asked Guo Xiaobei what he thought first.

After a moment of silence, Guo Xiaobei nodded.
