Fortunately, the Ministry of Officials did not embarrass Xu Jingzong, he took Chen Ying's letter, and successfully completed the entry procedures, of course, the long history of this county marquis, not even a sesame official, when Xu Jingzong came back, there was an extra copper tooth plate, a green official uniform, and a black soft foot.

took back the official uniform and head, Xu Jingzong couldn't wait to change it when he returned to the house. When Xu Jingzong, who was wearing a black official uniform and a soft-footed hood, appeared in front of Chen Ying, Chen Ying couldn't help but want to laugh.

The top of the hat in the Tang Dynasty has an arc upwards to form a semicircle, which is domed, and most of the feet behind the hat are drooping, which is similar to the rabbit's ears at first glance (interested friends can Baidu it). Moreover, Xu Jingzong is not good-looking, wearing an official uniform, he does not show his might and domineering, but is more like a rice bag on a big horse monkey.

Wugong Hou Mansion, that is, the original Xu Mansion, the original housing must not be able to live for Xu Jingzong anymore, even if Chen Ying is willing to give it, Xu Jingzong may not be willing to live. Xu Jingzong can't do it at least at the moment. At the end of the former West Cross Courtyard, it was originally Xu's guest room, and now it has become the residence of Shi Xu Jingzong, the head of the Wugong Marquis.

One of the three rooms was used for a study and utility room, one was carved out as a living room, and one was used as a bedroom for Xu or Jingzong.

Although Xu Jingzong was conscientious, at the beginning of his tenure, he took over the account book from Lan'er and carefully checked 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 said with a smile: "This person can't be idle at all, if Xu Jingzong continues to be so decadent, the whole person will be wasted." Now find him something to do, why not! ”

Lan'er said: "Lang Jun, Lan'er has been in charge of the accounts these days, but she is afraid and doesn't dare to make any omissions......

Before the words fell, he heard Xu Jingzong's voice coming from outside the door: "There is no omission, this is not necessarily, the accounts of the Hou Mansion not only have problems, but the problems are not small, full of 1,800 yuan!" ”

Hearing this, Lan'er's eyes were about to fall, she stretched out her hand and swore an oath: "Heaven and earth conscience, Lan'er didn't dare to be greedy for half a penny, if Lan'er was greedy for half a penny, even if Lan'er was greedy for half a penny, even if Lan'er had ten thousand arrows piercing her heart, she would not be able to die......"

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

Xu Jingzong hurriedly explained: "Miss Lan'er, don't misunderstand, it's not that Miss Lan'er is greedy for ink, but those tricksters who deceive Master Hou!" ”

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

Xu Jingzong said indignantly: "These 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 are generally divided into three types: money, materials and fields, of course, these three kinds of salaries are generally not fixed, and officials of the same level, due to different titles, have no honors, and their incomes are also different. For example, Chen Ying is now a commander general (both the Protector Army), which is the commander of the third rank, so Chen Ying enjoys the treatment of the official of the third rank plus the sixth-class founding marquis.

Chen Ying's Yulu includes the annual record of Yongye Tian, these Yongye fields include the post field and the title of the field, Chen Ying, the martial arts marquis, has 15 tilts of land, plus 9 tilts of the job field, in fact, he has 25 tilts (2,500 acres), this field can be passed on to his descendants, but it depends on the tax set by the officials themselves to determine the level of income.

Chen Ying did not set the tax rent for the field, so the responsible officials took advantage of their position to collect the rent according to the system of 15 taxes and 1 tax, according to which Chen Ying could receive at least 900 stone of grain.

In fact, Chen Ying watched it for a long time, but he was still confused, and he didn't notice the trickiness at all.

Xu Jingzong reminded Chen Ying, and Chen Ying understood. In fact. These officials actually collected rent according to the grain, but when they entered the accounts, they used chestnut rice to enter the accounts, and the price of grain in Chang'an was two cents more expensive than that of chestnuts per bucket. Nine hundred stone valleys were exchanged for nine hundred stone chestnuts, and the difference of 18,000 yuan disappeared.

Eighteen thousand yuan, that is, less than eighteen yuan, this amount of money is a drop in the bucket for Chen Ying. However, the important thing is that this is not a matter of more money and less money, and whoever is cheated by others will definitely not be happy.

Although the value is not high, her responsibility for dereliction of duty is indispensable. Lan'er suddenly blushed, not knowing what was wrong.

Chen Ying immediately picked up the pen and quickly calculated. In later generations, arithmetic is a compulsory course, basically most people can calculate the addition and subtraction within 10,000 by heart, Chen Ying will calculate the results, respectively, recorded in Arabic numbers, in just a quarter of an hour, Chen Ying will calculate the entire account book, in addition to this way of high price and low price, it is really as Xu Jingzong said, the difference is 18,000 Wen.

Xu Jingzong looked at Chen Ying's way of settling accounts, although it was different from him, but it was more than a hundred times faster than him, when Chen Ying exchanged 18,000 for 18,000, Xu Jingzong suddenly praised from the bottom of his heart: "Master Hou is also a master of arithmetic?" ”

Chen Ying said noncommittally: "The study of arithmetic cannot be popular in the world now, and pedantic scholars in the world denounce it as a left-handed sidedoor. How stupid is that, don't you know how important arithmetic is to the national economy and people's livelihood? People stand in the world, move, sit and lie down, eat and eat and sleep are really inseparable from this knowledge everywhere. If this study can be popularized in the world, the disaster of the troubled times can be stopped, and the rule of the prosperous era can be prosperous. ”

Xu Jingzong nodded approvingly and said: "For one term as an official, for the benefit of one party, if you don't know arithmetic, you can only be a confused official!" ”

Chen Yingdao: "Jingzong is also proficient in arithmetic? ”

Xu Jingzong said lightly: "I understand a little, I understand a little." For example, the chicken Weng one, worth five, the chicken mother one, the value of three, the chicken chick three, the value of one, 100 dollars to buy 100 chickens, ask Weng, mother, chick each geometry? Jingzong knew that there were three groups of answers, one of them, Weng fourteen, mother eighteen, and chick seventy-eight, two, Weng eight, mother eleven, chick eighty-one, and third, Weng twelve, mother four, and chick eighty-four. ”

Chen Ying smiled and said: "There is a method below, Mr. and below, each have a number, below 10,000,000, more than 10 million, add, subtract, multiply and divide each once, and finally list the four numbers, okay?" ”

For the calculation expert, the larger the number, the more difficult the calculation, the slower the calculation, although it is a purely low-level calculation, but it is very important to consider the calculation of the calculation and the proficiency of the use of the chip. This kind of competition has no fancy or much value, and is simply a mode of comparison between arithmeticians.

The beauty of Chen Ying's proposal is that each side will give an equal order of magnitude number, which is equivalent to the number that neither side knows the other party, so when calculating it, I am afraid that the other party has already calculated it to bluff itself.

Xu Jingzong patted the case and shouted: "Okay." Good! That's a fair way! ”

Chen Ying waved his hand and said with a smile: "Wait, how about winning?" What about the negative? ”
