"According to what I know, before the Northern Zhou Dynasty of the Sui Dynasty, there were 4.22 million households in the Northern Zhou Dynasty, and the Northern Zhou Dynasty was only half of the country, and the territory could not be compared with the current Tang Dynasty, so why is the number of households in my Tang Dynasty not as large as the number of households in the Northern Zhou Dynasty, let alone compared with the Sui Dynasty." Li Chengqian asked.

"Emperor Wu of the Northern Zhou Dynasty, Yuwen Yong, was a great talent, destroyed the Northern Qi and unified the north, and the population of households has reached more than three million, and then after a period of development."

"The population of the Northern Zhou Dynasty reached 4.22 million households, because there was no longer a war in the Northern Zhou Dynasty, the people lived and worked in peace and contentment, and lived a prosperous life, and later Emperor Wen of Sui Yang Jian replaced the Northern Zhou Dynasty and ruled the world!"

"Until the Great Cause years, the population of the Sui Dynasty increased to more than 9 million households, all because the Sui Dynasty was politically harmonious, and there was no need to fight on all sides like my Tang Dynasty."

"At the end of the Sui Dynasty, all kinds of anti-king uprisings, when I founded the Tang Dynasty, I only got the Central Plains, and other places were occupied by Dou Jiande, Wang Shichong and others, and the eastern and western Turks in the north were strong, and they were eyeing my Central Plains."

"After years of unification wars, the number of households in my Datang has changed from more than 9 million to 2 million."

"The Tang Dynasty has been fighting wars with the Turks in the north for many years, and there have been natural and man-made disasters, I don't know how many people have died, and it is not easy for the population to recover to the current number of households." Gao Cheng said.

Gao Fulfillment is right! The main reason is that the turmoil at the end of the Sui Dynasty led to a sharp decline in the population, and coupled with the continuous wars, the population was able to grow to more than 3 million households, which was not easy!

Li Chengqian didn't bother with the population, asked about some other things, and asked Li Xiang how he was doing recently, before letting Gao Cheng leave.

……

"I've seen the king!" The pawn of Honglu Temple ordered Wang Quan to bow his hand.

"The pawn order is something to see Your Majesty!" Wang Quan arched his hand and said, "I don't know if it's for that Fanbang's business?" ”

The Pawn Commander is the head of the Pawn Bureau, subordinate to the Honglu Temple, and his main responsibility is to manage foreign affairs and be responsible for entertaining foreign guests.

"The eldest princess of Honghua, who married Tuyuhun far away, came to Beijing to see Your Majesty! It is for this that I report to Your Majesty, Wang Eunuch, can Your Majesty be inside? Pawn Ling asked.

"Yes! Your Majesty is complimenting! Wang Quan said.

"Oh! In that case, I'm here and wait. The pawn order said, it is easy to smell when you go in now.

It's better to stay outside and wait, and wait for Li Chengqian to finish his work before going in, there will be no taste.

Although it is a big deal to report to the emperor that the eldest princess of Honghua has entered the court to meet the emperor, how can it be as important as the emperor's excretion.

While waiting, Dian Ke Ling and Wang Quan chatted with each other, until someone came out of the room and said that the emperor was finished, and then they walked in.

"The pawn of the Chen Honglu Temple ordered Zhao Xiang to meet His Majesty!" After seeing Li Chengqian, the pawn ordered to salute.

"No rudeness! Is it for a foreigner to come to me? Li Chengqian asked.

"Your Majesty! Queen Tuyuhun, my eldest princess of Tang Honghua wants to enter the court to see Your Majesty! The minister came to inquire whether it was arranged according to the old rites. Pawn Ling asked.

The eldest princess of Honghua was originally a daughter of the clan, but was later selected by Tang Taizong as a candidate for harmony, so she was named Princess Honghua and married Tuyuhun.

In terms of seniority, the current emperor Li Chengqian still has to be called the eldest princess of Honghua and an aunt.

After Li Chengqian succeeded to the throne, he crowned Princess Honghua as the eldest princess, which was the first time that the eldest princess of Honghua came to Chang'an to see the Son of Heaven since she got married.

Honglu Siqing handed over such a burden to the Pawn Bureau.

There was a disagreement in the Pawn Office for this matter, and some people thought that the standard treatment should be improved, after all, the eldest princess of Honghua even the emperor had to be called an aunt.

Other people are resolutely opposed, believing that all matters concerning the reception of foreign guests are clearly stipulated, as long as things are done according to the rules, there is no need to raise any standards, and this is not in accordance with the rules.

In short, neither side can convince anyone.

Therefore, the pawn order decided to leave this difficult problem to the emperor to decide, no matter what the outcome, as long as the emperor decides, the other party can only carry it out.

"No need! Receive it as it should be! Li Chengqian said.

This little thing is worth running to ask him, there is no need for a clan girl to deliberately raise the standard to entertain!

"No!" The pawn ordered to salute in response.

With the emperor's clear instructions, the next thing, needless to say, they also understood how to do it.

"When will the eldest princess of Honghua arrive in Chang'an?" Li Chengqian asked.

"Your Majesty! The eldest princess of Honghua will arrive in Chang'an in three days. Pawn Ling said.

"Then go back and get ready for this aunt of mine!" Li Chengqian said.

"No!" The pawn ordered the salute to retreat.

Since everyone has come to Chang'an, they always have to meet each other, and by the way, ask her about Tuyuhun's situation and what kind of attitude Tuyuhun has towards the Tang Dynasty's garrison in Dafeichuan.

and what kind of attitude Tuyuhun has towards Datang, whether it is friendly to Datang or secretly colluding with Tubo.

This is related to how Datang should treat Tuyuhun's policy in the future.

The eldest princess of Honghua is undoubtedly loyal to the Tang Dynasty, she will definitely not hide anything, and will tell him about Tuyuhun's situation.

Three days passed in a blink of an eye.

The eldest princess of Honghua and her entourage entered Chang'an, and under the guidance of the officials of the Pawn Bureau, they came to the post house to stay.

All the treatment here is done according to the treatment of the princess.

This time, the eldest princess of Honghua not only came to see the emperor alone, but also brought her son, Murong Zhonghei, to the court.

"Please also ask the eldest princess to rest here, tomorrow Your Majesty will hold a banquet in the Liangyi Palace for the eldest princess to catch the wind and wash the dust, the eldest princess mainly has any needs, you can send someone to tell me, the next official will definitely do it for the eldest princess." The official of the Pawn Office said.

"It's hard work! These are already very good, this princess is a little tired, you can step back first! If you really need it, people will come to you. The eldest princess of Honghua said.

"Then the official will leave!" The official of the Pawn Office said and turned to leave.

The next day, Li Chengqian held a banquet in the Liangyi Hall to formally summon the eldest princess of Honghua.

"The eldest princess of the Tang Dynasty Honghua and the queen of Tuyuhun, the Li family, pay a visit to His Majesty the Emperor of the Tang Dynasty!" The eldest princess of Honghua saluted.

"The foreign minister, Murong Zhonghe, the son of King Tuyuhun, pays a visit to His Majesty the Emperor of the Tang Dynasty!" Murong Zhonghei saluted.

"Excuse me!" Li Chengqian said.

"Thank you, Your Majesty!" The eldest princess of Honghua and Murong Zhongji thanked her.

"Auntie and cousin, take a seat! Today's banquet is specially arranged for my aunt and cousin. Li Chengqian said.

After the eldest princess of Honghua and Murong Zhongji took the table, they thanked Li Chengqian again and again for their hospitality.
