Does anyone know how many items are in our Palace Museum?
If you say the numbers, I believe it will scare many people. According to statistics, the collection of the Forbidden City has 20 categories, with a total of about 1.86 million pieces, of which there are more than 590,000 pieces of ancient books and documents alone.
For researchers, some jade artifacts and other cultural relics are very good to study, but in the face of such a huge number of ancient books, it is actually very difficult to study.
It should be known that the study of ancient books is not just as simple as classifying them, but also to study their content and then compare them with the ancient books of the same era, so as to fill in the blank history and examine the correctness of certain historical events.

With nearly 600,000 pieces of literature to be fully studied, how many researchers are needed to work around the clock?
However, as long as the study will certainly be fruitful, today's story is a discovered ancient book, a secret purpose of the Qing Kangxi period.
Of course, this secret message also reveals the background of his family, if it were not for this secret will, he would not know the other identity of his family, but it was hidden so deeply.
< h1 class="pgc-h-arrow-right" > apparent identity</h1>
According to the records in the canonical history, the Cao family was originally a slave of the Zhengbai Banner. After Dorgon's death, the Zhengbai Banner was taken back by Shunzhi, so the Cao family returned to the Ministry of Internal Affairs and became the emperor's domestic slaves.
As a close subject of Tianzi, there are naturally many opportunities, especially after the birth of the noble Kangxi, the wife of the Cao family has the honor of becoming his nanny.
However, kangxi was ill with smallpox in Beijing when he was young, and although Kangxi was taken out of the capital by Su Ma Lama and Lady Cao to hide, he still did not escape the clutches of smallpox, but fortunately, Lady Cao and Lady Cao did their best to take care of it, so Kangxi took back a life.
That is, from this moment on, the Cao family gradually developed.
As we all know, Kangxi is a person of great affection and righteousness, and he will treat the people close to him with sincerity, not to mention the Cao family who has the grace of saving lives, so when Kangxi became an adult, the Cao family arranged better official positions, and even Jiang Ning weaving, which many people could not ask for, gave the Cao family.
Of course, Kangxi not only gave this official position, but also directly showed his trust and attention to the Cao family from his actions.
For example, when an official of the Cao family went to Beijing to report for duty, Kangxi would stay overnight and talk at night with candles.
If you go down to Jiangnan, it is even more important not to live in the palace but to live in the Cao family.
All kinds of signals indicate that the emperor is the patron of the Cao family, and no one can shake it.
However, this point makes many people feel strange, it is reasonable to say that there are many people close to Kangxi, but why do they love the Cao family so much? Is it just because of the saving grace of the year?
Even if it was for the grace of saving lives, did he let the Cao family lose money and ignore it, and didn't he worry that the Qing Dynasty's Jiangshan would bring crisis because of it?
However, no matter how people in later generations guessed, they could not give a perfect answer, until they found a secret purpose from the Forbidden City, they knew that the cao Xueqin family had another identity.
<h1 class="pgc-h-arrow-right" > real identity</h1>
The content of the secret purpose is to talk about the meteorology, rice prices, public sentiments and even scientific expeditions in the Jiangnan region. But in such a case, it is good to go directly to the fold, why submit it through the way of secret folding?
In particular, the content is described in great detail, just like a report.
In fact, of course, you can't see anything directly in this way, but you can refer to the actions of Kangxi at the same time to get the answer.
Kangxi received the secret decree in early September 1711, but immediately after that, the largest fraud case of the Qing Dynasty appeared in Jiangnan, known in history as the "Jiangnan Fraud Case".
But Kangxi seemed to have known about this matter for a long time, and when it first happened, Kangxi investigated the case thoroughly with lightning speed.
As soon as the fraud case was over, Kangxi ordered officials to rectify the price of rice and solve a series of problems such as banditry.
If I were the governor of Liangjiang at that time, I would be very curious, why would Kangxi know these things, and did Kangxi have eyeliner in the liangjiang land?
Yes, the Cao family is the eyeliner that Kangxi planted in the Jiangnan region.
It is precisely because of the absolute trust in the Cao family, so on the surface to arrange a fat vacancy, it seems to be guarding the financial gate of Jiangnan for the emperor, but behind the scenes, he helps Kangxi to inquire about Jiangnan's every move, and even the weather conditions such as wind and rain are reported in great detail.
You know, although Jiangnan is a rich land, the mountain high emperor is far away, and it is an important position that leads the whole body.
If he didn't have a confidant to provide him with intelligence clues, how could Kangxi be assured?
<h1 class= "pgc-h-arrow-right" > the art of kings</h1>
In fact, let's carefully recall it, and the same is true of Yongzheng after that? Although he threw Cao Xueqin's family into the abyss, he sent a Li Wei to Jiangnan, which was similar to Kangxi's approach.
Therefore, if the emperor wants to be good, he must look at the six ways and listen to the eight directions, and have enough eyeliner or secret agents to stabilize his Country and Mountains, and the Cao family is undoubtedly one of them.
It's just that since it is the identity of the secret agent, others naturally can't know, even if there is some speculation, but with the support of the emperor, what can others do?
