"In addition to thanking Zhang Guan for curing my stubborn disease, there is another thing that I have to thank Zhang Guan for healing!"

Xu Yingfan's expression was straight, and he deliberately hung up the appetite of Zhang Zhongji and others.

"Oh, tell me?"

For Zhang Zhongji, a good businessman like Xu Yingfan is his parents, who can withstand countless pilgrims, and his expression and tone are just right.

"Haha, if I hadn't come to Xuangong Mountain to restore, how would I have been able to see Master Li Changqing's Danqing Wonderful Pen?", Xu Yingfan said with a smile on his face.

"Mr. Xu is so praised!", Li Changqing smiled slightly.

"Mr. Xu is a big name in the world of calligraphy and painting, and being so praised by Mr. Xu shows that Mr. Li's paintings must be extraordinary, but it's a pity that I can't see them!", Zhang Zhongji said with a sigh of regret.

"Zhang Guanzhu is also very good at painting, and the opportunity is rare, why don't the two masters exchange painting skills?"

Xu Kangping felt that his father attached too much importance to Li Changqing, and wanted to use Zhang Zhongji to suppress Li Changqing and make Li Changqing lose face in front of Xu Yingfan.

"Hehe, how dare some clumsy tricks show ugliness in front of Mr. Xu!"

Zhang Zhongji's eyesight is not comparable to Xu Kangping, from Xu Yingfan's attitude towards Li Changqing just now, it can be seen that Li Changqing's painting skills are by no means idle, and the painting of exchanging painting skills is too risky.

"Just now Mr. Li said that he is also a doctor, why don't you let Zhang Guanzhu help grandpa check his body first, and then let Master Li check it, isn't it safer to compare the two?"

Xu Xuantong hated Li Changqing for saying that she was 'infertile', and seized the opportunity to fan the flames and add fuel to the fire.

"Mr. Li is a teacher at the Wen'an College School of Medicine?"

Xu Yingfan saw the flag held by Qiu Lexian and others on the way up the mountain, and knew that Li Changqing and the others were all teachers of Wen'an Academy, and thought that Li Changqing would be a teacher of the Academy of Fine Arts, but who knew that Li Changqing was actually a doctor, so he asked in surprise.

"It's true that I'm a doctor, but I'm just teaching mathematics at Wen'an College in my free time!", Li Changqing didn't expect Xu Xuantong to come to such a sentence.

"Li Changqing? I remember, I remember that half a year ago, there was a person who proved Goldbach's conjecture and had a great impact in the world, that person is from Wen'an City, also called Li Changqing, could it be you?"

Many stories will slowly become obsolete in time, when Li Changqing proved Goldbach's conjecture, the whole country shook and the country was paying attention, only half a year has passed, everyone can't remember the name of the person who proved Goldbach's conjecture, Xu Xuantong studied finance in college, and is closely related to mathematics, so he paid a little attention to it, and suddenly remembered that there was such a thing.

"It's purely a game!", Li Changqing said very blandly.

"Solving the problems of the mathematical community for hundreds of years, picking off the crown jewel of mathematics, is just a game...... it can be loaded with B, but I like it! This kind of stamp is interesting and commemorative!"

Xu Xuantong's eyes lit up when she looked at it, and among the stamps she had collected, there were popular little fresh meat, temperament idol uncles, and hip-hop rappers, but there were no special stamps of the cold scholar type.

"Master Li's game has completed the work of countless people who have exhausted their life's energy for hundreds of years without success, and it has greatly added glory to our Huaxia!"

Hsu Young-fan did not know mathematics, but he also knew the significance of proving Goldbach's conjecture.

"Although the previous research was not successful, it taught us that those methods were not feasible, and it was I who stood on their shoulders to prove the Goldbach conjecture, and all those who studied this subject have contributed, not just me!"

Li Changqing summed up a lot of failed experience at the beginning to successfully prove Goldbach's conjecture, and those who paid for this proposition did indeed contribute a lot.

"Master Li's remarks are enough to make most of the experts and professors in China who are chasing fame and fortune ashamed!"

Living with kindness, such as entering the room of Zhilan, Xu Yingfan felt the charm brought by Li Changqing's noble character and felt very comfortable.

"Since Mr. Li only teaches at Wen'an College in his free time, then Mr. Li's main job is to work in a hospital?"

Xu Kangping felt that Xu Xuantong's proposal was very good, and asked Li Changqing to help Xu Yingfan check his body, and then let Zhang Zhongji review it, bringing the topic down to Li Changqing's doctor's profession.

"I mainly farm in the mountains, raise chickens, study, and occasionally go to the village health center to help!", Li Changqing shook his head and denied.

"My Abba came to restore this time, and I want Zhang Guanzhu to check it again, if Master Li is also a doctor, can you help my Abba take a look?"

Xu Kangping felt more and more that Li Changqing loved to exaggerate, a farmer who farmed in the mountains, read a few books, and dared to call himself a doctor when he was doing chores in the health center in the mountain village, maybe he didn't have the qualifications to practice medicine, so he wanted to expose Li Changqing's true face in front of Xu Yingfan, and said deliberately quietly.

"Little thing!", although Li Changqing has no obligation to help Xu Yingfan check his body, he can refuse completely, but Xu Yingfan is not bad, so he agreed.

"Then I'll throw bricks and lead the jade, and I bother Mr. Xu to stretch out his wrist!"

Zhang Zhongji squinted his eyes and asked him to compare his medical skills with a rural lang, if it weren't for Xu Yingfan, if he were someone else, he would have slammed the door and left.

"Trouble Master Zhang Guan!", Xu Yingfan rolled up his sleeves and put his wrists up in front of Zhang Zhongji.

"Mr. Xu's pulse is calm and gentle, not floating or sinking, not slow or counting, not fine or flooding, the rhythm is even, and the stomach is angry, there are spirits, and there are roots, everything is normal!"

Zhang Zhongji put his finger on Xu Yingfan's pulse and said after a moment.

"It's all the blessing of the Lord, last year I came to Xuangong Mountain, I didn't have the strength to walk a few steps at the foot of the mountain, and this year I climbed through the Yunguan narrow pass from the mountain gate in one breath, and went directly to the Muzhen Temple!"

Xu Yingfan also felt that he ate and slept soundly, and it was not difficult to go up to the fifth floor in one breath, and there should be no problems with his body, and he was in a very comfortable mood after being confirmed.

"Abba, let's take a look at Master Li again, maybe Master Li has a different opinion!", Xu Kangping said.

Xu Kangping and Xu Xuantong sang and harmonized, but how could Xu Yingfan not see the intentions of his son and granddaughter? His son is too small, and his granddaughter likes to mess around outside, and his dignified 'Chai Daguan' in the field of calligraphy and painting has not had a qualified heir to the heirs who bought 9,000 pairs of master-class paintings for 200,000 yuan to open peace painting shops at home and abroad!

"No need, Zhang Guanzhu said that everything is normal and there is no need!", Xu Yingfan said a little lonely.
