After cleaning up, He Beichen helped Gu Mai carry the basket to the hospital.

Gu Mai thought about how to solve the problem of exchanging fine grains for coarse grains, after all, she had to solve the problem of food and clothing. "Big brother, do you know where to get coarse grains?"

"I know a place where we can try it, but there aren't many people who change the fine grain, so we can't change it right away."

"Okay, if I know where it is, I can go there tomorrow and wait." Thinking that she was now recuperating in the hospital, there was nothing to do.

"Let's go."

Then He Beichen led her to an alley, and then walked into a house.

In broad daylight, this one is also locked.

In these years, there is nothing in every house, the law and order is good, and the people are simple, so everyone basically does not close the door, and it is still rare to lock it like this.

He Beichen knocked on the door, and a voice came from inside. "Who?"

"Find Aunt He." He Beichen said.

The visitor hurriedly opened the door, and a middle-aged woman with her hair in a bun and dressed in blue walked out. "It's Beichen, hurry up and come in. What's going on today, let's see if I can help. ”

"Third aunt, this little sister wants to exchange fine grains for some coarse grains from you." He Beichen took out the grain and showed it to He Sangu.

He Sangu is the aunt of He Beichen's relatives, and she didn't come out of five suits. Usually I secretly do some small business, so I am very enthusiastic.

Originally, she particularly hated He Mi's family, who had no money and were lazy, but He Beichen was an exception.

He Sangu looked at these fine grains. "Where did all this come from?"

She looked Gu Wheat up and down as if she were a thief. Look at this dress, it doesn't look like you can afford to eat fine grains.

Gu Mai could tell what he meant from the other party's expression. "Of course it's my own family, otherwise where could it have come from."

He Beichen asked directly. "Can you change it?"

He Sangu is just a sneaky business, she is all speculative, can she still manage others? "I have a few women here who regularly come to change fine grains, but the demand for fine grains is really not high, and I am still in danger, if I am really found out, I will be caught in it, and I will parade the streets."

Gu Mai understood what this meant by pulling my wife, that is, she wanted benefits. "Auntie, just say, how much coarse grain can I exchange for my four catties of fine grain."

"Four catties of fine grain can return fourteen catties of coarse grain, you see if it's okay, if it's okay, I'll help you change it."

Two catties of coarse grain are missing, Gu Mai thought to himself.

"Third aunt, deducting two catties of food is too much." He Beichen couldn't stand it and said.

"Then I can't help it, that's what I earned." He Sangu only said with interest in her eyes.

Gu Mai bargained. "It should be less than four catties of fine grain here, but three catties and eight taels are absolutely there, I want to exchange 15 catties of coarse grain, is it okay?"

He Sangu picked up her pocket and weighed it, and sure enough, it was three catties and eight taels high. "Okay, for the sake of being a child, I'll change it for you. However, these fifteen catties of coarse grain are 10 catties of cornmeal and 5 catties of sorghum rice. ”

"Okay." Gu Mai readily agreed.

Cornmeal is very good, and my godmother's family eats cornmeal every day, so it is much more convenient for people to cook.

"Okay, look, it's definitely high." He Sangu weighed the cornmeal and sorghum rice so that she could see it clearly.
