This is just the surface, I don't know how many people who are looking for Lu's father in private and want to ask Lu Zi'an to come out to talk about the preface.

Lu's father looked at Lu's mother's condemnation and was confident: "Although they looked for me, I didn't agree." ”

After all, he Tai Chi beat the thief six!

"But Zi'an, you also have to think about it. Lu's mother looked solemn: "People are afraid of being famous, pigs are afraid of being strong, you can handle this matter well, if it's not good, I'm afraid it will be gossipy." ”

There are more monks and less porridge, and whoever responds will offend others.

Lu Zi'an really didn't think about this question, he groaned slightly, but he didn't think it was a big deal: "If I really want to write a preface, I won't choose anyone." ”

"Why?" Lu's father and Lu's mother were a little surprised.

Lu Zi'an's idea is very straightforward: "Because the preface is to give people a preliminary understanding of some of my thoughts and the original intention of writing this book, no one knows better than myself what kind of book I am writing." ”

"There is some truth in saying this...... Dad Lu frowned slightly and thought: "But if you write it now, is it too late?"

"It's in time. ”

In fact, when it was decided to write the preface, Lu Zi'an had already sketched out the general content of the preface in his heart.

He wanted to write about the original intention of the book and, of course, what he was about to do.

And before that, he needs to do something that has been stranded for a long time.

After many days, Lu Zi'an finally turned on the live broadcast again.

He said on Weibo three hours in advance, and after preparing some materials, he opened the live broadcast room on time.

There was jubilation in the live broadcast room, and there were nearly 30,000 people.

"Hello everyone, long time no see. After Lu Zi'an opened it, he just said hello, and the barrage instantly filled the screen.

[My husband looks at me, I miss you so much!]

[Love you for 10,000 years! Ask for the flop!]

[What kind of cards are you turning over for a man, anyway, I'm the first to say it!

[Yo, you're the first, it's great, Lin Xiangru is on top of me for his tongue?]

[I am General Zhao, and I have the great merit of siege and field warfare!]

[Hahaha neurosis, you guys, then there is Zhuge Liang's tongue battle group Confucian!]

【…… Suddenly I couldn't look directly at my language texts. 】

Lu Zi'an smiled, and waited for the barrage to gradually decrease, before continuing: "Of course, I haven't seen you for so long, and I can't disappoint everyone, today I have prepared a more interesting work......

All barrage came to an abrupt halt.

Produced by masters, it must be a high-quality product.

Lu Zi'an's works, each one will not be repeated, what surprise will he give them now?

There is no selling, and there are not many meaningless actions.

Lu Zi'an sat down in front of the workbench and dragged a box over.

Listening to the movement, you can tell that the box is heavy.

Lu Zi'an took a few pieces of materials and brought them up, and while taking the carving knife for preliminary processing, he said slowly: "Before making it, I want to introduce to you the 24 solar terms in my country. There is a record in the "Zhou Li": the scenery in the south of the day is short and summery, the scenery in the north is long and cold, the east is windy and windy, and the west is cloudy. This is the initial outline of our 24 solar terms. ”

24 solar terms......

The crowd fell into deep thought.

"In fact, before that, I wrote an application, and with the approval of my superiors, my country has already applied to UNESCO for the 24 solar terms. Lu Zi'an understated and said these surprising words, but he still looked indifferent: "The 24 solar terms, which perfectly combine astronomy, phenology, agriculture and folk customs, have been used by our people for thousands of years, which is our important "index" and precious wealth. ”

His voice was calm and gentle, but his hand movements did not pause for half a minute.

The carving knife gently slashes from the jade material smoothly and naturally, the knife is clear without traces, and the fingertips are gently stroked, and you can feel the warmth of the jade.

However, with a few knives, a round jade ball was already gently rolling in his palm.

Seeing this scene, the old man Zhuo in front of the computer couldn't help but take a soft breath: "How do I feel, this Zi'an's skills have improved ...... again"

I once thought that gold and silver were wrong, which was the pinnacle of Lu Zi'an's jade carving skills, but he never stopped.

After the baptism of Youyi enlightenment, Lu Zi'an's skills have been improved.

The jade materials he selected were not all mutton fat jade, some even had variegated colors, but more of them were pure jade.

They come in a variety of colors, and some are even rough in appearance, with only a faint glimmer of light in the cracks.

Lu Zi'an didn't know about everyone's surprise, he gently scraped on the jade material, with a hint of pampering in his eyes: "The twenty-four solar terms are part of my country's time frame, and the ancients divided the annual movement trajectory of the sun into 24 equal parts, and then subdivided into seventy-two phenology, so that production and life are very closely combined with nature, and this is of great significance for people's cultural identity and national cohesion." ”

Many people only know the names of some of the more important solar terms about the 24 solar terms.

I don't particularly know what it is about and what it represents.

Therefore, in addition to some praise and meaningless water barrage content, there are also some people who have raised objections.

[IMHO, I probably can't remember this, after all, it doesn't mean much to me.] 】

[Yes, Master Lu also said that this solar term is beneficial to production and life, but we generally use the solar calendar. 】

[I have a lunar birthday, but the solar terms don't seem to be lunar calendars, right?]

Every time he made a jade ball, and then took the material, Lu Zi'an would take a look at the content on the screen.

After reading these words, he was not angry.

He put aside the matter at hand, and said in a slight mutter: "Zhuangzi said in "Knowing the North Tour": "Heaven and earth have great beauty without saying, there is a clear law at the four times without saying it, and everything has a reason without saying it." "The great beauty of heaven and earth, the sequence of the four seasons, and the withering and glory of all things are all caused by the great power of nature, and cannot be changed by man. The 24 solar terms are not only a valuable astronomical calendar system in ancient China, but more importantly, the social value behind it. ”

The 24 solar terms began in the Warring States period, and then went through countless dynasties, step by step refinement, and finally had today's 24 solar terms.

When Lu Zi'an was doing and explaining, many people began to frantically check the information and classics.

It turns out that a seemingly simple solar term contains so much magical knowledge.

Just like the question asked by some people: why do solar terms correspond so well to the Gregorian calendar as a lunar calendar, such as Qingming is always on April 5?

Why do you sometimes read the news that the solar terms are not only dated, but also accurate to the minute and second?

Why do I sometimes think that the 24 solar terms are quite accurate, and sometimes they are not?

All questions are gradually answered as we slowly understand.

The solar calendar is the solar calendar, while the lunar calendar is the lunar calendar, and both are revised according to the changes of the sun and moon.

The solar terms, on the other hand, are lunisolar calendars.

It is both a solar calendar and a part of the lunar calendar, taking the long of the two and discarding the shorter of the two.

It is the crystallization of thousands of years of wisdom of the ancient Chinese people!

The more I know, the more I feel.

At that time, there was no auxiliary tool, only to use the extremely crude Gui watch to record the time, the ancients were able to figure out the division of solar terms, really, amazing!

Of course, while feeling emotional, people still pay great attention to Lu Zi'an's works.

As time went on, there were more and more jade balls on the table.

They made some very interesting discoveries: these jade balls are large and small, round and flat, and some are even just thin slices.

What is this?

Countless barrages were puzzled, but Lu Zi'an always just smiled lightly: "If it's a spoiler, it's not interesting, let's look down!"

There are more and more people in the live broadcast room, and the later ones don't know what happened in front of them, but they only think that Lu Zi'an cut a table of jade balls is very strange.

Just when many people were full of curiosity, Lu Zi'an brought up a complete piece of jade.
