"This is the account book, look at this, this is my demonstration, write the price and goods, see it clearly and understand, and settle the account quickly." Changshuang taught Liang Shengming to use modern bookkeeping methods.

Liang Shengming was able to understand it at one point, so he nodded again and again, "Miss Chang is really smart, so it saves a lot of trouble." ”

"Then I'll go out for a walk and come back to you in the afternoon." Changshuang wants to see the street market here.

"Okay, I'll be sure when the girl comes back." Liang Shengming said with a smile.

"I see that the inkstones you make are not only finished products made according to the drawings I draw, but also made by yourself, Brother Liang only needs to calculate the sales of the goods made according to my drawings."

Liang Shengming sent Chang Shuang out, and nodded again and again, "The girl is reasonable." ”

Walking on the streets of Anhe County, Mu Qingtian said happily to Chang Shuang: "Shuang'er, you are too powerful!" ”

"I'll know after reading more books, let's see what good cash crop seeds are here, and I want to buy them."

"What is a cash crop?" Mu Qingtian was puzzled.

"To put it simply, it's a valuable crop."

"Oh, what does Frost want to plant?"

"What is worth what you grow." Chang Shuang's mind is full of making money.

Crops with economic value, generally speaking, are cotton and sericulture, because people need cloth to cover them, which is indispensable.

Then there are many crops that can produce oil, such as peanut oil, sesame oil, soybeans, and vegetable oil.

Cotton requires long-term care and is annoying when picking, and Chang Shuang hardly thinks about planting this. Peanuts are good, there are soybeans at home, and she wants something of value that is rare.

"That's rice." Mu Qingtian was the first to think of this, Mi Ke is compared to a pearl.

"I don't want to grow crops other than rice, and I don't want to grow things that need water all the time." Chang Shuang didn't want to be too troublesome, so she felt that she was too picky.

"That's hard to find, our place...... Although it is not our county, there is nothing rare in this small place to the south. "Mu Qingtian doesn't understand crops.

"Just ask the store." Mu Qing Tiandao.

Chang Shuang walked around the street for a long time, and finally returned empty-handed. Anhe County also has things in Anshou County, so there is no need to bring them back from here.

Chang Shuang was tired and took Mu Qingtian to eat in the restaurant.

"Shuang'er, if you want rare good things, you have to go to the big city, and there are rare ones in it." Mu Qingtian looked at Chang Shuang with some trouble.

Chang Shuang drank the tea, sighed and said: "I mainly want to make money, I can settle for rare seeds without me, as long as the growth period is short, and I can sell it to make money, it's fine." I don't really want to plant something that is harvested once a year. ”

"If you want to grow fast, then you only have vegetables, you can harvest them once a month, but vegetables are not very valuable." Mu Qingtian scratched his head, his head could only think of this.

"Dish? I also thought, what is good? ”

Chang Shuang has already planted turnips, what else does people like to eat, whether ordinary people or rich people?

Convenient to eat, vegetables that can be cooked raw and can be eaten......

Cucumbers, tomatoes, lettuce, turnips......

These are fine when eaten raw in modern times, but here they may be said to be sick, except for cucumbers. It is not clear if there are tomatoes here, and she has never seen this vegetable here.

Chang Shuang thought about it carefully, cucumbers seem to take almost a year of growth, it takes time, and if you plant it, it will be troublesome, she doesn't want to do it, and her family is lazy, so if she grows it, she has to hire someone.
