After that, Fang Xuanling asked about Arabic numerals, addition, subtraction, multiplication and division, and multiplication formulas. After the student explained, many of the important ministers were in a fog and were at a loss, but Pei Ju (ju), the secretary of the Tang Dynasty, and Yan Lide, the secretary of the Ministry of Industry, couldn't help but light up their eyes.

Pei Ju was born in the wealthy family Wenxi Pei family in Wenxi County, Bingzhou.

Wenxi Pei's family, passed down from the pre-Qin Ying surname, first flourished in the Wei and Jin dynasties, and reached the peak in the Tang Dynasty. They belonged to the Guanlong aristocratic group, first loyally followed the Tang Emperor Li Yuan and the state uprising, and then became the most loyal followers of Li Shimin, the son of the Tang Dynasty. The Tang Dynasty has only been founded for nine years now, but the Wenxi Pei family has seventeen family children who have achieved the number of high-ranking officials of the Tang Dynasty, and the number of people is at the top of all the big families, second only to the number of high-ranking officials of the Longyou Li royal family.

Wenxi Pei's family rose from the Wei and Jin dynasties to the present, in just 400 years, there have been 59 prime ministers, 59 generals, 14 Zhongshu waiters, 55 Shangshu, 44 waiters, 8 queens and princesses, 21 horses, 288 people who served as assassins, 288 guards, 89 people, 33 people, it can really be said that there are many talents, and they will meet the martial arts and princesses, and they are the real wealthy families.

The world has analyzed the reasons for the prosperity of the Wenxi Pei family. Everyone thinks that there are three main reasons, namely, the Pei family's family motto of "emphasizing education and discipline, advocating literature and martial arts, promoting both morality and industry, and being honest and self-disciplined", and attaching great importance to education and the self-improvement of the clansmen.

Other important ministers may not have realized the importance of Arabic numerals, addition, subtraction, multiplication and division, and multiplication formulas, but Pei Ju, the secretary of the household department, and Yan Lide, the secretary of the Ministry of Industry, who deal with money, grain, population, materials, and projects all day long, know the practical value of these knowledge, which will be very simple and accurate to calculate all kinds of data, and greatly improve the efficiency of the household department and the Ministry of Industry in the Tang Dynasty. Therefore, Pei Ju and Yan Lide together proposed to the head of the ministers, Shangshu Zuo Servant, and the Ministry of Officials, Shangshu Fang Xuanling, requesting that the backbone of the household department and the Ministry of Industry be sent to Zhongnan Mountain to learn Arabic numerals, addition, subtraction, multiplication and division, and multiplication formulas.

Seeing Pei Ju and Yan Lide jointly requesting that as the left servant of Shangshu in charge of the six departments, Fang Xuanling immediately figured out the key. They immediately agreed to their request.

Soon the important ministers left Zhongnan Mountain together, and they reported to the Tang Emperor Li Shiminyu: "The knowledge taught by Li Xuan, the king of Yong'an, is the most simple and practical knowledge. The students are also hungry and thirsty for learning, and they forget to sleep and eat. ”

When the Tang Emperor Li Shimin learned that the students lived in the thatched huts they had built separately, he immediately ordered: "All the materials that have just been prepared for the renovation of the palace will be transported to Zhongnan Mountain to build houses for the students." ”

Cui Gan, the secretary of the Ministry of Rites, immediately stood up and advised: "Your Majesty, my Tang Palace was repaired decades ago, when Yang Guang, the former Emperor Yang of the Sui Dynasty, had just ascended the throne. Now it is dilapidated, and many palace rooms have begun to leak. This time, the imperial court went to great lengths to raise timber and other materials, just to make His Majesty and His Majesty's family in the palace live more comfortably, Your Majesty is the honor of all vehicles, how can you wronged yourself and transport the materials to Zhongnan Mountain for the students to use? ”

Li Shimin said slowly: "Although the palace is dilapidated, it can still be lived in after all. The 2,000 students on Zhongnan Mountain are the hope of my Datang in the future, and they are dedicated to studying. It's for themselves, but it's also about the future of my Datang. I can't let them go without a place to live in order to study. Although I am a little wronged now, I will wait until the students have returned from their studies. My Datang will be full of talents, and it will become stronger and stronger, and the people of Datang will also be able to profit and become more and more prosperous. Education is a major event that will benefit the future generations. I can't help but pay more attention to it. ”

Li Shimin's words moved the ministers of the imperial court to tears.

On Zhongnan Mountain, when 2,000 students knew that His Majesty the Tang Emperor had actually used the building materials for the construction of the palace. When they were all transported to Zhongnan Mountain and built a residence for them, the students were also moved to tears. They studied harder, and in just two and a half months, all of them thoroughly mastered the Chinese pinyin, Mandarin, Arabic numerals, addition, subtraction, multiplication and division, and multiplication formulas taught by Li Xuan.

Li Xuan was very surprised at the learning progress of the students, which was the main course in the first and second grades of primary school in later generations, and the students only took two and a half months to learn it thoroughly.

Li Xuan asked each student to write down their interests and hobbies, and then divided them into classes according to their interests.

In Li Xuan's heart, he knows that the best education is to teach students according to their aptitude. According to each student's strengths and hobbies, we teach them the most suitable knowledge. Every student has his own different talents and different life experiences, so every student should have the most suitable learning knowledge for him, the most suitable path for him, rather than teaching the same knowledge like later generations, cramming education, so that in the end, everyone learns the same and has the same ability, forming a surplus of talents, resulting in employment difficulties and serious waste of talents.

For students who like politics and military affairs, Li Xuan gave them the historical novel "Romance of the Three Kingdoms". The scheming, change, and strategy in the book "Romance of the Three Kingdoms" are enough for them to learn for a lifetime, and this book is biased towards the vernacular, and the story is wonderful, which is most suitable for students from fourteen or fifteen to twenty years old. Su Dingfang, who entered Zhongnan Mountain to study, was even more fascinated by this book all of a sudden, he read this book overnight, and he couldn't put it down. The storyline of this book made his blood boil after reading it, and he was deeply touched by military strategy. He looked at his mentor Li Xuan on Zhongnan Mountain with adoring eyes, and secretly admired it in his heart. Seeing Su Dingfang's admiring eyes, Li Xuan was also secretly proud. He knows this student named Su Dingfang, in history, Su Dingfang can be said to have a particularly high status in the Tang Dynasty, he is the fourth leading commander of the Tang Army, leading the national army, and has made great achievements. The first is Li Shimin, the king of Qin of the Tang Dynasty and the current son of the Tang Dynasty, the second is the god of the Tang Dynasty, the first person in the Tang Dynasty military is Li Jing, the first auxiliary general, the third is the current champion general Li Ji, the fourth is Su Dingfang, and the fifth is Pei Xingjian, who Li Xuan first met on Wudang Mountain. It is under the leadership of these five that the Datang army has won a hundred battles, is invincible, and invincible, so that it has played the great military power of the Tang Dynasty. The book "Romance of the Three Kingdoms" is said to be a must-read book for dignitaries and generals in the early years of the Qing Dynasty. With such a wonderful storyline and a book of high practical value, how could Su Dingfang, who loves military affairs, not like it in his heart? (To be continued......)

PS: Two shifts a day, although it is very hard, but I will continue to persevere until the end of the book. Thank you for your support!
