Fortunately, the Ministry of Personnel Examination did not make things difficult for Xu Jingzong. He took Chen Ying's trust and successfully completed the entry procedures. Of course, the chief of the county marquis was not even a sesame official. When Xu Jingzong came back, he had a bronze tooth card, a green official uniform, and a black soft-footed head.

After taking back the official uniform and the head, Xu Jingzong returned to the house and couldn't wait to change it. When Xu Jingzong was wearing the gang's long boots, wearing green official uniforms, and wearing soft heads, appeared in front of Chen Ying, and Chen Ying couldn't help laughing.

The top of the Tang Dynasty's turtle hat was curved upwards to form a semicircle, which was dome, and most of the legs behind the hat were drooping. At first glance, it looked similar to the ears of a rabbit (interested friends can use it on Baidu). Moreover, Xu Jingzong was not very handsome and looked majestic in his official uniform. Instead, he looked more like a rice bag on a big horse monkey.

The Marquis of Wugong, which is the original Xu Mansion, would definitely not be able to live in Xu Jingzong. Even if Chen Ying was willing to give it to him, Xu Jingzong might not be willing to live there. Xu Jingzong could not do the task of snatching the main guests at least. At the end of the former West Crossing Courtyard, it was originally the Xu family guest room, but now it has become the place for Xu Jingzong, the chief of the Marquis of Wugong.

Three rooms are used for a study room, a living room, and one is opened to be a living room, and one is also used as a bedroom for Xu or Jingzong.

Although Xu Jingzong fulfilled his responsibilities, he took the account book from Lan'er at the beginning of his tenure and carefully discussed the accounts.

During dinner in the evening, Lan'er's mouth pouted to the sky.

Chen Ying naturally knew that Lan'er was dissatisfied with Xu Jingzong's seizure of her financial power.

Chen Ying smiled and said, "This person cannot be idle at all. If Xu Jingzong continues to be decadent like this, he will be ruined. Now find something for him to do, why not do it!"

Lan'er said: "My husband, Lan'er is worried about the accounting these days and dare not make any omissions..."

Before he finished speaking, he heard Xu Jingzong's voice coming from outside the door: "There is no omission, this is not necessarily the case. Not only is there a problem in the accounts of the Hou Mansion, but the problem is not small, with a total of 1,800 yuan!"

Hearing this, Lan'er's eyes were almost falling off. She reached out and sweared: "The conscience of heaven and earth, Lan'er dared not greedy for half a penny. If Lan'er greedy for half a penny, even if Lan'er pierced his heart, he would not die well..."

"What a mess!" Chen Ying glared at Xu Jingzong and said, "Lan'er, I can trust it!"

Xu Jingzong quickly explained: "Miss Lan'er, don't misunderstand it. It's not that Miss Lan'er is greedy, but those foolish officials and deceive the marquis!"

Hearing this, Lan'er and Chen Ying looked at each other and Chen Ying asked, "What's going on?"

Xu Jingzong said angrily: "These tricky officials are really hateful!"

Xu Jingzong took the account book and pointed it out to Chen Ying one by one.

The salaries of officials in the Tang Dynasty were generally divided into three types: salary, salary materials and job land. Of course, these three types of salaries were generally not fixed. Officials of the same level had different titles, whether there were any honorary officials or not. For example, Chen Ying is now a general of the honorary officials (he has been promoted to the Guardians). This is a third-rank official, so Chen Ying enjoyed the treatment of a third-rank official and a sixth-rank founding marquis.

Chen Ying's salary includes the annual Yongye Field, which includes the division of the field and the title of the title. Chen Ying, the Marquis of Wugong, owned 15 yuan of land and nine yuan of land. In fact, he owned 25 yuan (2,500 acres). This land can be passed on to his descendants, but it depends on the rent and tax set by the officials themselves to determine the income.

Chen Ying did not formulate tax rent for the job land, so the responsible officials took advantage of their position to collect rent according to the system of 15 taxes and one tax. According to this regulation, Chen Ying could receive at least 900 stones of grain.

In fact, after watching for a long time, Chen Ying was still confused and did not find any tricks in it.

Xu Jingzong reminded Chen Ying, and Chen Ying understood. In fact, these officials actually collected rents according to millet, but when they entered the account, they used chestnut rice to enter the account. The price of grain in Chang'an is two cents more expensive than that of each bucket of li. The nine hundred stone valley was exchanged for nine hundred stone chestnuts, and the difference of 18,000 coins disappeared.

Ten thousand yuan, which means only eighteen coins, is a drop in the bucket for Chen Ying. However, what is important is that this is not a question of how much money it costs. Anyone who is cheated by others will definitely not feel happy.

Although her value is not high, her dereliction of duty is indispensable. Lan'er's face suddenly blushed and didn't know what she was wrong.

Chen Ying then picked up the pen and calculated it quickly. Arithmetic was a compulsory course in later generations. Basically, most people could calculate the addition and subtraction within ten thousand with their hearts. Chen Ying recorded the calculated results in Arabic numbers. In just one quarter of an hour, Chen Ying calculated the entire account book. In addition to the method of high-price collection and low-price purchase, it was indeed as Xu Jingzong said, with a difference of 18,000 liters.

Xu Jingzong looked at Chen Ying's way of calculating accounts. Although it was different from him, it was more than a hundred times faster than his speed. When Chen Ying changed 18,000 to 18,000, Xu Jingzong sincerely exclaimed: "It turns out that the Marquis is also a master of calculations?"

Chen Ying said unanimously: "The study of sci-calculation cannot be widely used in the world now, and the pedantic scholars in the world denounce it as a side door. How stupid is that? Don't you know how important it is to national economy and people's livelihood? People stand in the world, sit and lie down, eat and sleep, and sleep in food and clothing. If this study can be very popular in the world, then the disasters in troubled times can be stopped and the governance in prosperous times can be prospered."

Xu Jingzong nodded deeply and said, "As an official, he will benefit the people. If he does not understand arithmetic, he can only be a confused official!"

Chen Ying said: "Jingzong is also proficient in arithmetic?"

Xu Jingzong said lightly: "I understand a little bit, understand a little bit. For example, the chicken one is valuable, the chicken one is valuable, the chicken one is valuable, the chicken three is valuable, the chicken one is valuable, and the chicken one is valuable, and the chicken one is valuable, and the chicken one is worth a hundred yuan to buy a hundred chickens. Ask the Weng, the mother and the chick one? Jingzong knew that there were three groups of answers, one is Weng four, the mother eighteen, the chick seventy-eight, the second is Weng eighty-eight, the mother eighty-eight, the chick eighty-eight."

Chen Ying smiled and said, "But there is a way to get a number, sir and sir, each of them will be less than tens of millions, each of them will be added, subtracted, multiplied and divided once, and finally list the four numbers, which is OK?"

For experts in planning, the larger the number, the higher the calculation, the slower the calculation. Although it is purely low-level calculation, it considers the memory of the math and the proficiency of the use of the tool. This kind of competition is not a trick or very valuable. It is purely a model used by mathists to show off their abilities.

Chen Ying's proposal is that both sides each have a number of the same order of magnitude, which is equivalent to both sides not knowing the number of each other. When calculating in this way, they are afraid that the other party has calculated it and is going to scare him.

Xu Jingzong slapped the table and shouted: "Okay. OK! This method is fair!"
