As Chang'an gradually approaches the Spring Festival, Chang'an has gradually become more and more lively, and now in the Tang Dynasty because of the progress of printing technology again, the cost has been reduced again, and the cost of various papers is gradually decreasing.

In the winter of this year, the Datang calendar formulated by the Taishi Bureau under the Ministry of Culture began to be sold to the public for the first time.

This calendar can be regarded as the expansion task of Li Ke in order to build the printing plants that Datang Daily built in various parts of Datang.

Using the cheapest and worst quality paper, the printed calendar contains 365 days of the year, as well as the Gregorian calendar and the lunar calendar, which are like the calendars of later generations, and also prints some suitable and taboo things.

Anyway, these things are just small things for the Taishi Bureau, and it's nothing to roughly calculate the time of a year, they are all traditional arts, and it is very cheap, so a calendar was compressed to a penny by Li Ke.

This is almost the cost, it doesn't make money, if you count the freight, Li Ke allows it to sell at a maximum of 2 Wen.

2 If Wenqian is placed in the early years of Zhenguan, this number can almost be said to be an astronomical amount for ordinary people, but for today's Datang, this number is not an astronomical number.

It can be said that almost all the people have consumed, because of the exemption of agricultural taxes and other reasons, the people have a certain amount of money in their hands, although it seems that 2 yuan to buy a calendar, it seems that there is some luxury for the people.

But in fact, what is recorded on these calendars is still very important to many people.

The reason why Li Ke is in a hurry to promote this is because in this era, the calendar is to some extent one of the most important ways to expand the Tang culture and expand the influence of Chinese culture.

You must know that with the establishment of Pei Xingjian's Central Huazhou Theater, the dating method of the Tang Dynasty was in Tianzhu, and Persia and other countries quickly began to spread.

They may not use the chronology of how many years of Datang, but they all use the same method as Datang, that is, how to calculate how many days a year and how many times a day.

Because Datang's way is extremely precise, unprecedentedly accurate.

The division of time zones is not a difficult task for the current Tang Taishi Bureau, and after the time zone division is completed, the time calculation of each region is naturally based on Chang'an time, and then the time of each time zone is calculated.

And these local countries are naturally very favored by these Tang Dynasty era with accurate timing.

In order to cooperate with the promotion of the Tang era and time, Li Kedu has already asked people to sell Tang clocks and watches to Persia, Byzantium, and Arabia.

If they want to use time, they naturally have to use the way of these epochs, no matter how they name the year, it doesn't matter how many years it is for Emperor So-and-so of Persia, or how many years of Persia.

At least their New Year's time, the day of each month and other times are the same as Datang, and this is enough.

Civilization is the witness of time, and time is the carrier of civilization.

Without the witness of civilization, time naturally has no meaning of existence, and similarly, without time as a carrier, civilization cannot precipitate and become thick.

It may seem like a simple calendar, but it can enhance people's sense of participation, substitution, and belonging to the country.

Because on this simple calendar, it shows not only the time, but also the accumulation of thousands of years of culture.

Weeks, festivals, history, and so on are all condensed into this small calendar.

Although this year's calendar is a little anxious, some small stories can be printed on the calendar of each year in the future, with historical stories as the main body, and all the knowledge of astronomy, geography, and humanities of the Tang Dynasty is contained in vernacular.

Although each page is only a brief introduction, for people who may have never left their village in their lives, this knowledge can greatly expand their horizons!

The reason why an ordinary person can become a talented person in ancient times more than a thousand years later is because under the impact of countless information, even if it is passively received, their brains are filled with a lot of knowledge.

This knowledge may seem useless in modern society, but in ancient times it had a great impact.

In the same way, why are the people of this age so ignorant because they have no access to any information? And this calendar is one of the channels.

It doesn't need to be precise, how advanced the knowledge is, it only needs to record a lot of common sense, and this common sense is a huge improvement for all the people.

In the process of understanding this knowledge, they are understanding Chinese culture, and in the process of understanding Chinese culture, they are increasing their sense of belonging, so that they can constantly and repeatedly confirm that they are a Tang Dynasty.

It can be said that this knowledge is continuously hinting at them from the subconscious, implying that they are a Tang Dynasty!

At the last big court meeting before the New Year of the 27th year of the Tang Dynasty, Li Ke sat on this dragon chair, and his spirit was somewhat trance-like.

Although a year has passed, it always feels as if many years have passed, the main thing is that this year has changed too much, not to mention anything else, last year he was just a prince, but this year he is already an emperor.

It's okay to become the emperor, now his father went to play in Guangzhou, Hainan, and the queen mother and concubine Jinyang all went with them, Jinyang is said to be coming back in the middle, and then I don't know why I didn't come back.

Maybe it's because the weather on the road is too cold, and my dad is not at ease.

As for his eldest brother, he didn't come back from Liaoning Prefecture at all, but his sister-in-law moved out of the East Palace the day after Li Ke succeeded to the throne.

Li Ke asked people to ask, saying that it was arranged by his eldest brother.

What else could he say? In the edict that Li Shimin asked Qin Qiong to convey to the whole country through the Ministry of Security, there was not only the edict of the Zen position, but also Li Chengqian's own renunciation of the crown prince's position, saying that his talent could not inherit the documents of the Tang Dynasty.

It can only be said that Li Ke ignored the Ministry of Security at the beginning, or that he ignored the hearts of the people.

He can be said to have been in charge of the country for the past two years, and he is used to arranging things through various departments such as the Ministry of Security, and when his father arranges things in his name and says that he will be affected, all the members of the security forces and other members of the Ministry of Security below should not be too good at secrecy.

And the intelligence department is all from the Yuelai Firm, and the people from the Joy Firm will certainly not object to the matter proposed by His Highness.
