Chastity Layman 2

Chapter 669 Li Chunfeng

Changan.

Although the sky is still snowing, the first month has passed and spring is here, but the coldness of spring is still severe in February.

On a snowy afternoon, the Provincial Political Hall under the door is warm and cozy. As the highest authority in the Tang Dynasty, the Political Hall can now be said to be in charge of all kinds of officials, assigning government to the world, allowing six positions, and assisting the emperor to govern.

The natural conditions in this kind of yamen are the best, not to mention that it is safe and quiet in the imperial city, even the yamen has long been equipped with floor heating, the ground is all laid with pottery pipes to pass hot smoke, and the walls are all safe. With a smoky fire wall, you don't even need to turn on the stove if you stay in the house.

Smokeless and odorless.

However, Qin Lang is still used to putting an iron stove in the house. It feels like something is missing in the winter without a fire. What's more, sitting on the iron stove with a pot of water can also be used for humidification. Roasting on the stove also has a special flavor.

"Meet Li Chunfeng from Taishi Bureau!"

Officials in brown robes reported outside the door.

"pass!"

The door was pushed open, and a young official in a blue official robe came in, stood at the door and saluted Qin Lang.

"General Shilang, Li Chunfeng, Secretary of the Taishi Bureau, pays respects to Qin Pingzhang."

Qin Lang got up, picked up the teapot from the iron stove, picked up an upside-down chai-sand teacup and poured him a cup of black tea, and then took out a roasted taro with slightly charred skin that exuded an attractive aroma.

"Close the door and sit down. Here I have freshly baked sweet potatoes, paired with black tea, just to warm my body."

Facing the popular prime minister who was seven or eight years younger than himself, Li Chunfeng was quite generous, thanked him, came over to pick up tea and taro, and sat on the seat by the stove.

Qin Lang sat down on another chair in front of the stove.

"Do you know why I called you here?"

"I guess it's because of the calendar."

Qin Lang nodded, sat in front of the stove and patted the sweet potato in his hand, patted off the dust and peeled off the fluffy taro skin, revealing the fragrant and glutinous taro paste inside.

"Since the founding of the Tang Dynasty, I first followed the Sui Dynasty's great career calendar. In the second year of Wude, I also issued the "Wuyin Yuan Calendar" written by Fu Renjun and Cui Shanyong, a Taoist priest from Dongjun. But in the first year of Zhenguan, you wrote a letter Did the imperial court point out eighteen questions about this calendar?"

Although Li Chunfeng, 30 years old this year, was recommended by Liu Wenjing to join Li Shimin's army when Datang was first established, his official position is very low now.When he first met Qin Lang, he reported that his official position was General Shi Lang in charge of Taishi Bureau Secretary Li.

Jiang Shilang is only a prose grade from the ninth rank, and Si Li, as a staff officer of the Taishi Bureau, is only from the ninth rank. Add a shou word.

It stands to reason that the official shouldn't be so young. After all, Qin Lang found out about Li Chunfeng because of something, and he was really surprised when he found out that he was a ninth-rank official, especially when he found out that he had been under Li Shimin's command since the founding of the country.

The Taishi Bureau is a subordinate yamen saved by the secretary. The chief Taishi Ling is a fifth-rank official. In the ninth year of Wude, it was the Taishi Ling Fu Yi who gave a secret performance to the Supreme Emperor Li Yuan. If the king of Qin should have the world, Li Shimin would be very dangerous.

The yamen of the Taishi Bureau was also called Qin Tianjian in the past. Its duties were to test astronomy and determine the calendar. It reported the measured sun, moon, stars, wind and cloud, and climate to the imperial court every day. Dates of weddings and other important ceremonies.

The official position of the calendar is to govern the calendar of the country, and to create the calendar to be distributed in the four directions.There are six Lili, one Li doctor, 55 Li students, and five Li students.

Li Chunfeng is the chief calendar judge of the Datang calendar. He has a few small officials and a group of students. The calendar judge.

Li Chunfeng has been the official of Si Li for four years.

It was at the beginning that he wrote a letter to point out the shortcomings of the previous calendar. Later, Li Shimin gave him the title of Si Li, and gave him Jiang Shilang, a loose official from the ninth rank.

Now seeing that Li Chunfeng is young, tall and energetic, he can't help but curiously ask why the first year of Zhenguan is a real person from the ninth rank.

Li Chunfeng didn't mind, and told Qin Lang directly that he used to be a Taoist priest, and he joined the army when he joined the Qin Dynasty's palace in the Tang Dynasty.Later, because he was appointed by Li Shimin to the post of Si Li, he officially accepted the official rank.

I was originally a Taoist, so I didn't care about official rank.

These words made Qin Lang admire.

After eating a roasted taro and drinking a cup of black tea, Qin Lang also understood Li Chunfeng's experience. This year, 30-year-old Li Chunfeng was born in Qizhou, Guanzhong. His father was a county official in the Sui Dynasty. He simply resigned and became a Taoist priest.However, his father was very talented. He had annotated "Laozi", wrote ten volumes of local chronicles, and even compiled an introductory book on ancient astronomy, "Ode to the Elephant in Astronomy". Read widely, especially interested in astronomy and mathematics.

At the age of nine, he entered the temple to learn Taoism from a teacher.

At the age of 16, he was recommended by Liu Wenjing to join the army in the Office of Recorder of Prince Qin's Mansion.

Later, because he pointed out that there was a problem with Fu Renjun's calendar, he was awarded the post of Li Shimin by Li Shimin, and he was responsible for revising the calendar.

"It's been four years since you held the position of secretary of the calendar. I don't know how the revision of the new calendar is going?" Qin Lang asked.

"Back to Qin Xianggong, Fu Gong is a very famous astronomer. The Wuyin Yuan Calendar compiled by him and Cui Yuanwai is a calendar that calculates time based on astronomical phenomena. It is also the first calendar in Chinese history that uses the Dingshuo method. The calculation methods of the calendar, such as daily profit and contraction, monthly slowness, etc., are roughly the same as the Daye Calendar, and the Daye Calendar itself is based on Liu Zhuo's Huangji Calendar."

Qin Lang didn't understand these things, but he knew that the calendar was extremely important to all dynasties.

"Is there anything wrong with this calendar?"

"Back to Qin Xiang, using the Dingshuo method, it is easy to have accidents of consecutive big moons or even small moons. According to this calendar, by the 19th year of Zhenguan, there will be four consecutive big moons."

Qin Lang knows that the ancient calendar has a lot to do with astronomy and arithmetic, and it is a very advanced thing. He must not be able to understand these things himself, but he also knows that the lunar calendar used in later generations is actually a kind that was only improved in the Ming and Qing Dynasties. The calendar, which has been mixed with some Western algorithms at that time, is very different from the calendar at this time.

"Then Li Sili found a solution?"

"It is difficult to avoid this kind of accident with the traditional method of determining the moon, unless it is innovated."

"I just want to know if you have a good calendar out?"

"Yes, I have been researching a new calendar for the past few years. I don't plan to use the old Pingshuo method, but use Dingshuo again and create an original Jinshuo method. According to the specific situation, push the new moon up or down by one day, so that the corresponding big month becomes smaller or the smaller month becomes bigger, so as to solve the accident that violates daily habits such as four consecutive big months or three small months. ..."

Qin Lang didn't quite understand these very professional things, but he also knew that Li Chunfeng had indeed done a lot of research on astronomy, mathematics and calendars, and seemed to have researched a better calendar.

"When will it be available?"

"It's available now."

"Is it better than Fu Yuanwai's calendar?"

"More precise!"

Qin Lang nodded in satisfaction, "That's good, you hand in this calendar, and I will submit it to His Majesty for approval to issue and replace the old calendar."

Li Chunfeng didn't expect Qin Lang to trust him so much, it was a surprise.

"If Prime Minister Qin gives me some more time to study, I can still improve the problem of precession in the new calendar."

Qin Lang smiled and said, "It's okay to study and improve after the promulgation." He was in a hurry to promulgate the new calendar because he planned to use the new calendar as an opportunity to take advantage of the opportunity of the Quartet to come to the court to show respect to those who were attached to the Tang Dynasty. The feudal vassals issued calendars and announced Zhengshuo.

Zhengshuo is the beginning of a year, Shuo is the beginning of January, and Zhengshuo is New Year's Day.Since ancient times, the calendar and political rule have been closely related. Which month is the first month and the first day of the month is the first day of the year. This is determined by the highest political power, which is the Zhengshuo.

It is said that the lunar calendar of later generations uses the Yin month as the first month, and it is said that it is the Zhengshuo of the Xia Dynasty, so the lunar calendar is also called the Xia calendar.And Yin Jixia turned over the previous month and took the ugly month as the first month, and Zhou Jiyin turned over the previous month and took the zi month as the first month.

The imperial court determined Zhengshuo and issued calendars to the ruled areas and subordinate vassals, announcing Zhengshuo, which was a major event to determine the unification of the world.

The duty of describing Taishi in the Zhou rites is to promulgate to the government and Dubi in the first year of the year, and to promulgate to Shuo Yubangguo.

Feng Zhengshuo was an important symbol of the vassal's recognition of the authority of the central dynasty.

The son of heaven is respectful to Chengtian, and the princes are respectful to the king, none of them is more important than Zhengshuo.

Announcing the privilege of Zhengshuo is a symbol of having the right to rule from heaven. The granting of the calendar is a symbolic ruling power for the dynasty to exercise the authority given by heaven and to formulate the rhythm of time. Accepting Zhengshuo is to recognize the ruling power of the dynasty and identify A symbol of this ruling order.The symbolic ceremony of promulgating the Bushuo, which is repeated every year, continuously strengthens the existing ruling structure.

"This time, the envoys from the four Haidong countries, as well as Turks, Xue Yantuo, Tuyuhun, Dangxiang, Gaochang and other countries, will bring back the new calendar of the Tang Dynasty, Fengzheng Shuo, and change it to the Tang Zhenguan year."

Even the timing will be based on Chang'an's day and night time as the standard for promulgating the world's time, so as to express the sacred duty and mission of the emperor of the Tang Dynasty to grant the time to the people on behalf of Tianjing.

In the future, the Tang Dynasty and the surrounding vassal states will implement Chang'an time to record the time, use the Zhenguan Year Number to record the year, and adopt the Datang calendar to Zhengshuo.

"The new calendar, temporarily named Huang Tangzhen Guanli!"

"Goguryeo and Japan also granted calendars, Feng Zhengshuo?" Li Chunfeng was a little suspicious.

"Anyone who dares to disobey Zhengshuo will be punished!" Qin Lang smiled slightly, as if saying that the taro was a bit powdery.

Hearing this domineering declaration, Li Chunfeng could only shut up and leave.

Qin Lang wanted to ask him if he could really deduce that the heroine would proclaim the emperor, and the Wu family would replace Tang, so think about it or forget it!
