The snowy Chang'an is always cold, but a kind of honeycomb coal that has quietly emerged on the market in Chang'an has imperceptibly dispelled the cold winter.

In the midst of the silver-covered streets, there are bursts of mist rising from the towering chimneys of the houses, and the small stove for burning honeycomb coal has quietly spread in Chang'an.

This small and lightweight burning material is very affordable and durable, at first it was used by some poor families who could not afford to burn firewood and braziers, and then gradually developed to the residents of the whole Chang'an, and finally even those dignitaries in the city began to use this new material with a long burning time and large heating capacity.

You only need to open a chimney in the house, and you can enjoy the warmth of the cold winter without fear of charcoal poison.

Chang'an, north of Taiji Palace, the main hall.

At this time, in the main hall, Empress Changsun was roasting around the fire with Li Chengqian and Li Tai, two princes.

Empress Changsun looked at her two children with a loving face, and said softly: "Gao Ming, Qingque, yesterday I heard that your father went to the study to inspect the calligraphy you wrote, and I heard that the two of you are doing well, and today you can bring the calligraphy you wrote, and Eniang wants to see it." ”

Li Chengqian and Li Tai hurriedly took out a pair of notebooks from their arms, respectfully presented them to the eldest grandson, and said in unison: "Please take a look at the queen mother." ”

Empress Changsun smiled and took the notebook written by her two sons, and looked at it with satisfaction, only to see that Li Chengqian wrote a poem called "Tong Caring for the Ancients".

"The peaks and mountains are like gathering,

The waves are like fury,

Mountains and rivers surface Tongguan Road.

Wangxidu,

Hesitation.

Sad Qin and Han meridians,

The palace and all the rooms were made of soil.

Xing, the people suffer;

Death, the people suffer. ”

Empress Changsun's originally relaxed smile gradually became stern as she finished reading this poem.

When Li Chengqian saw the change in the eldest grandson's expression, he thought that his mother was dissatisfied, and hurriedly said: "The child's writing is not good, please punish the queen mother." ”

Empress Changsun reacted at this time, and asked with a playful smile: "Gao Ming, you wrote this poem?" ”

Li Chengqian was puzzled in his heart, and hurriedly said: "This word was not written by Erchen, but was taught by Xu Guigu before, and Erchen felt that the words written in this article rhymed, so he wrote it down, and the queen mother and father asked exactly the same question when they saw this word." ”

The eldest grandson smiled even more playfully, and after muttering a few words about Guigu, he turned his head to Li Chengqian and said: "Gao Ming, you are still young and can't understand the transcendence of this article. The meaning is profound, and the feelings are depressed. The majestic scenery and such incisive discussions, the three are perfectly combined, and the words are full of vicissitudes, which has the characteristics of nostalgic poetry and a unique depressing style. ”

Li Chengqian listened to a lot of things that Empress Changsun said as if he didn't understand, he only knew that the queen mother was happy.

After reading Li Chengqian's poems, Empress Changsun's interest was obviously higher. "Qingque, what about your writing? Is it also made by the descendants of Guigu? For Li Tai's youngest son, the eldest grandson seems to be more fond of him.

"After returning to his mother, it was Xu Guigu who made it, but unlike the eldest brother, the words of Erchen were obtained by Erchen and Xu Shi."

"Oh? What is written? Do you want my child to beg for it himself? "Empress Eldest Sun was very curious about the calligraphy written by Li Tai.

Took the copybook, "Qinyuan Spring." The seven big characters of "The Virtuous Queen Gao Feng" came into view.

"The love is sent to the country, the name is in history, and the reputation is engraved.

Praise the fairy and elegant rhyme, born a good couple; Lan Xin is qualitative, and the land creates a good marriage.

The fragrance is full of clouds, the sun and the moon are fragrant, and a generation of Shuyuan is a saint.

Graceful and can, make Danqi more colorful, and add points to the community.

Directly Chen Wai relatives should be cautious and persuade his brother to resign as prime minister.

More training children are humble and thrifty, and the dynasty continues; The ministers are loyal, and the emperor is brilliant.

Tasting Jin Luan, Dezhao Jiuding, the virtuous queen Gao Feng Baishizun.

Zhaoling Wang, sighing the love of husband and wife, the couple is deeply affectionate. ”

The eldest grandson queen was in a good mood for some reason today, and took the two princes to the Chang'an Academy that had just been built.

Mr. Li Gang greeted him personally, and now it is a cold winter moon, and the snow in the shade of the eaves has not yet melted.

Li Gang was wearing a strange fat clothes, and he invited Empress Changsun to sit in the academy with a white breath.

"Why is Master Li wearing such a fat shirt?"

"The queen doesn't know, this is the latest down jacket launched by Xujia Zhuangzi, with built-in goose down, which is extraordinarily warm."

The eldest grandson still followed Li Gang into the academy with some doubts, and just entered the academy, the most conspicuous thing was a few red circles on a large open space.

Empress Eldest Sun stretched out her white neck from the mink and asked as she looked, "Master Li, what is that red circle?" ”

Mr. Li Gang said lazily: "Oh, there is a stadium over there, which will be reserved for the students of the academy to exercise in the future." ”

The eldest grandson stopped talking and followed Li Gang towards the dean's office of the academy.

After three months of day and night work, most of the other buildings have been completed, except for a few three-story teaching buildings that have not been built.

In the entire academy, except for the dean's office, none of the buildings were built in the style of the Tang Dynasty, and Li Chengqian and Li Tai were amazed.

"Master Li, why is that house domed?"

"Cheng Qian, there is the Planetarium, there is a stargazing mirror in it, after the school starts, the Taoist Li Chunfeng will teach there, if you are interested, next time you can go to Yuan Tianshi and go stargazing with him, the key to the Planetarium is only the two of them."

"Master Li, why is there so much prey piled up at the door of the house over there?"

"Qingque, that house will be the place where the medical school will be taught in the future, and now the Taoist medical saint Sun Simiao is rushing to Chang'an, I don't know what Xu Gong showed him, this medical saint is now non-stop, it is estimated that he will be able to reach Chang'an Academy in two days."

The academy is very large, the dean's office is in the deepest part of the academy, a small courtyard house, the chimney is smoking, the place is small, but several people who live in it are very big people, Mr. Lu Deming Yuen Long of the Three Dynasties, Mr. Yan Zhitui, the imperial historian, and even the Empress Changsun has to pay a visit to these people.

Mr. Yuen Long and Yan Zhitui were making tea in the house, and when they saw the eldest grandson queen coming in, Yan Zhitui smiled and said, "I haven't seen you for a long time, but my carefree complexion is getting better and better." ”

Empress Eldest Sun rarely showed the posture of her youngest daughter, and said: "Mr. Yan is laughing, you are always strong-boned, and now that you go out to teach, the scholars of the world are blessed to hear the words of the sage again." ”

Yan Zhitui smiled and said: "Old and old, if it weren't for Yuen Long calling the old man to come together, the old man would have planned to enter the ground, Erlang's body is fine, and the world is not so easy to handle." ”

Empress Eldest Sun said: "Erlang is in good health, but the injuries he suffered in the early years will still be a little painful on a rainy day." It's okay to get a big deal. ”

Yan Zhitui seemed to remember something, and said, "By the way, why did you want to visit the academy suddenly today?" ”

Empress Changsun seemed to hesitate, and paused for a moment before saying: "Today, Qingque showed me a poem, and in a good mood, I allowed Qingque to make a request, and the queen mother will definitely meet him, and this baby's request is to come to the academy now." ”

"Oh? What kind of poem can make you, a talented girl who was known as the first of the three boudoirs in Guanzhong, also feel good? ”

Empress Changsun seemed a little embarrassed, and twisted it for a while before taking out Li Tai's notebook. RS
