Moreover, Wang Zheng's banknotes only have two types: ten-cent and one-hundred-cent. Not only are they easy to print, but the value is also large enough that ordinary people cannot exchange many of them.

The amount of paper money that Li Jingye needed to exchange was 200,000 strings of cash. A person's monthly salary was two strings of cash. Excluding those who returned home and those who joined the army, there were about 90,000 people left out of the 100,000 Tubo troops. 200,000 strings of cash was enough for circulation for the time being.

This salary is considered relatively low in Chang'an, even in the suburbs, but Li Jingye also provides food and accommodation for the Tibetans, so two strings of cash a month is about right.

Following Wang Zheng's suggestion, Li Jingye exchanged 20,000 strings of banknotes for 10 wen each and 180,000 strings of banknotes for 100 wen each. As for the change of one wen, it would be better to use copper coins directly. This would not only allow a comparison between paper money and copper coins, letting the people know which one is more convenient, but also prevent the depreciation of paper money.

Although there were only 200,000 strings of paper money, Wu Yi sent ten horse-drawn carriages to help Li Jingye transport it back. However, it was a thousand times lighter than copper coins.

Li Zhi mobilized 10,000 imperial guards to help transport the 100 million strings of cash by boat, but it took three days to transport it from the Taiji Palace to the Ninth Courtyard of the Grand Steward's Office.

Many people believe that the biggest reason why the public security in the Tang Dynasty is better now is that there is more money in circulation. Since money is easy to earn, people naturally don't need to steal or rob. After all, if you have trouble moving the copper coins you earn in a year, it is not cost-effective to steal or rob.

Wang Zhen smiled and said, "It's still early, we have to wait for others."

The New Year is coming soon, and this is the peak season for consumption in Chang'an. Specialties from all over the country will be shipped to Chang'an in large quantities at this time.

Still on the Wei River, thirty miles downstream from Chang'an, Wu You looked at Di Renjie with a resentful look on his face and said viciously: "It's all your fault. If it weren't for your boatmaster not giving way, I would have almost reached Chang'an now. If there is another accident later and I can't reach Chang'an today, I will see how I will deal with you."

Fang Zan wiped the wet corners of his eyes and nodded in agreement, "That's true. However, although it is big, it has a stale air. It is not as vibrant as our Baoan City. It won't take too long, at most two years, for our Baoan City to surpass it in area."

For this reason, housing prices in the south of the city have not risen in recent years along with the prosperity of the Tang Dynasty, but have become a little cheaper than before.

Di Renjie was too lazy to explain. He said he was sailing at a normal speed and did not violate any regulations. There was no reason for him to give way. However, he could only consider himself unlucky when he met such an unreasonable man.

The busyness of the money houses lasted for more than half a month before it eased. As time entered the twelfth lunar month, Chang'an became covered in silver, and the endless stream of coal smoke became an embellishment every day.

Fang Zha looked up at Wang Zhen with admiration. Wang Zhen patted him on the shoulder, sighed and said, "Let the past go. Cherish the future and that's what life is all about."

Di Renjie smiled bitterly, bowed to Wu You and said, "Grand Steward, please forgive me."

Although the Wei River is already in its dry season, thanks to the many large reservoirs built this year, the sluice gates will be opened to release water at the end of the Chen hour, so sailing throughout the day is still guaranteed. Anyway, it will not be too late to store water during the spring flood season next year, and some subsidies can be obtained for releasing water for sailing this year.

The Grand Steward's Mansion and the Imperial Palace are both in the north of the city. In winter, the wind is mostly northwest, and the coal smoke from floor heating and kangs has little impact on this area. However, life in the south of the city is a bit difficult, with coal dust falling from the sky every day.

Fang Numa nodded heavily, "Disciple understands, sir, thank you!"

Passing by the wholesale market, Zhang Gou looked at the lively scene inside and wanted to go down for a stroll, but the boat under his feet showed no sign of stopping.

To this end, last year Li Zhi specially established a large wholesale market outside the East City Gate so that more and more merchant ships could unload goods and trade nearby.

There was a hint of sourness in Fang Zhao's disdainful tone. This was once the place he had always dreamed of returning to. The Fang family's glory began here and was also destroyed here. If he wanted to restore everything for the Fang family, he had to return here. However, there was no need for that now.

Zhang Gou looked at the tall and wide walls of Chang'an City and sighed with admiration: "I didn't know Chang'an City is so big. It would take half a day to walk around the walls. Brother, don't you think so?"

Wang Zhen smiled and said nothing more. Zhang Gou looked at his teacher and his senior brother and said nothing more, for fear of accidentally touching his senior brother's sadness. Instead, he looked at the ships coming and going.

"Sir?" Zhang Gou looked at Wang Zhen with some confusion.

Zhang Gou knew that this was the east of the city, and the Grand Steward's Mansion was in the north of the city. The master would not stay here. After all, the master had not seen the master for many years. He should be very eager now, right? Wang Zhen looked back at the hourglass above the cabin door, and after a moment of hesitation, he said to Zhang Gou: "It's still early, let's go down and take a walk."

He should have listened to the steward and not come back this year. However, the millions of banknotes and bills were too important to be handed over to others. Waiting for a few more months would not be conducive to the development of Lhasa and Qinghai. So Di Renjie stayed up all night to sort out the political affairs of Lhasa and hurried back to Chang'an.

In the past, any larger ship, even a flat-bottomed boat, could not reach the city of Chang'an in winter.

Unexpectedly, he met such a difficult master and offended him. No matter what he tried, it was useless. Di Renjie couldn't help but sigh: It's really hard to deal with smart people when they become unreasonable.

Bobo came out and smiled at Wu You: "My wife told you to stop making noise. If you wake up little Bobo, you will have to pay for it."

Wu You was furious. "What compensation? We'll be in Chang'an soon. I'm not afraid of her. If she makes me angry, I'll tell my master about it and let him punish her and you as well."

Bobo's face turned bitter, and he shrugged his shoulders towards Di Renjie, indicating that he could do nothing to help. Di Renjie bowed to him to express his gratitude.

Wang Ying's voice came from inside the cabin, "Come back, the little girl is homesick and upset. If you can't persuade her, just ignore her. I hope Master Di will forgive her."
