Li Shimin exchanged all the things he brought. He brought Chu Suiliang, Yan Liben, Fang Xuanling, Du Ruhui, Wei Zheng and their paintings and calligraphy, and there are quite a lot of things that can be exchanged.

In addition to these famous calligraphy and paintings, Li Shimin also brought some antiques, including bronzes, porcelain, etc., so the value is good, and there are many things that can be exchanged.

In this way, Li Shimin bought a lot of tens of thousands of catties of grain, about thirty or forty books, and about a dozen kinds of vegetable seeds that add up to dozens of catties.

When the father and son left the store, these things filled the room.

Fortunately, after Li Shimin found out that all the things he bought would fill the room, he sent someone to expand the room. Now tens of thousands of catties of grain are piled up here, and the room has not been filled.

Li Shimin ordered people to come over and remove all the food in the house. Food is very important to Li Shimin and the others. Even these tens of thousands of catties of food may not be enough to eat.

Li Shimin thought about going to change a little later. Anyway, the store is there, and it seems that there should be a lot of food, so he can change it often. It's not that he spends money such as gold, silver and copper to buy, and pays for some paintings and calligraphy, especially the paintings and calligraphy are his subjects, then Li Shimin does not feel that the food is expensive.

"What did you buy?" When Li Shimin ordered people to move the food, he also called the palace servants to help him remove the books and seeds he bought. The books he bought about agriculture and breeding were going to be handed over at some time. to the person in charge of this.

Li Shimin was very curious about what his son bought. Li Chengqian, as the prince of the Tang Dynasty, actually didn't have much money, but he had many teachers' paintings and calligraphy here.

As a prince with countless teachers, his teacher would leave a lot of calligraphy and painting copybooks when he was teaching him. As long as he exchanged these calligraphy and painting copybooks, he could exchange a lot of things.

"Baby bought some recipes, and a dictionary." Li Chengqian gathered the books in his hand and said to Li Shimin, "My mother seems to have a bad appetite recently, and the child is thinking of buying some recipes for the people in the dining room to study and look at. Let's see if I can make my mother eat more."

He was telling the truth. Empress Zhangsun in the late pregnancy didn't have a good appetite, especially when it wasn't extravagant and wasteful, and she didn't have too much to eat, so she ate less.

As a son, Li Chengqian also knew that his mother was pregnant and had a hard time. When he went to the store, it was not only because he wanted to taste the dishes on the menu, but he also wanted his mother to eat something delicious and eat more. to be able to give birth to younger siblings in good health.

Li Shimin looked at his son and saw that in addition to a thick dictionary, he had several cookbooks in his hand, but he didn't say anything.

"Let me see what this dictionary looks like." Li Shimin was quite interested in the dictionary, especially after his son introduced him.

Li Shimin took the dictionary, and then Li Chengqian taught his father how to look up the dictionary while recalling what Zhang Chengchuan told him before.

Li Shimin read the dictionary while listening to his son's words, and nodded with satisfaction, "It's very good, especially this pinyin, it's very good."

Li Shimin couldn't put it down, but after looking at his son, he decided to buy another copy when he went to the store next time, so he should study it hard for his son.

"Brother, what did you buy this time?" When Li Chengqian followed Li Shimin to the Lizheng Palace, Li Tai and Li Lizhi both ran to him and asked.

The last time they had delicious food, this time they didn't know what their Aye and brother had exchanged. To be honest, they were curious.

"Bought some books." Li Chengqian put down several cookbooks, and the colorful cover immediately attracted the attention of Li Tai and Li Lizhi, but Li Tai paid more attention to the dictionary.

"Xin...hua...dictionary?" Li Tai looked at his eldest brother suspiciously, what is this book? What is the content?

"This is a dictionary, similar to Erya." Li Chengqian handed the dictionary to Li Tai and explained.

"It's the same as "Erya"?" Li Tai became more curious, and after turning it over, he found that the words were all missing arms and legs, but when he turned to the back, he found that some words were similar to theirs, that is The fonts are just different.

The fonts commonly used in the Tang Dynasty are regular script or official script, but most of them use regular script. And the font of "Xinhua Dictionary" is Song type.

But this did not affect reading. Li Tai looked at the words on the dictionary and asked, "Why is this word so small? How did it get written? Even if it is a book, can it print such small words?"

"I don't know, that shop is amazing, so it's not surprising that there are any strange things about these books." Li Chengqian said.

"What are these?" Empress Zhangsun looked at the recipes brought back by her eldest son and asked him with a smile.

"These are all the recipes that the baby changed. The baby bought some when he saw that the book cover was very beautiful. According to the introduction of the clerk, we can make all these recipes here. I bought some recipes and planned to let the dining room study it." Li Chengqian explained.

"Gao Ming has a heart." Empress Zhangsun smiled.

"Auntie, this one called cold cowpea looks delicious, should a vegetarian dish be eaten?" Li Lizhi asked, pointing to a dish planted in the recipe.

Because of the thriftiness of the royal family, it is difficult for emperors, queens, concubines, princes and princesses to eat meat. Li Lizhi ate meat once when Aye Aniang went to exchange. I haven't eaten meat in days.

It doesn't matter if you don't have meat, the vegetarian dishes on this look delicious too, I don't know if I can eat them.

"Auntie, this book has written a lot of tofu recipes. Stir-fried tofu, stuffed tofu, fried tofu, stewed tofu, tofu stewed fish head, tofu soup, etc. There are many tofu dishes." Li Lizhi opened a book When I saw the book, it turned out to be all tofu dishes, so I happily shared it with my grandmother.

In fact, the dish of tofu was not popular in the Tang Dynasty. Even though the practice of tofu has been handed down since the Han Dynasty, very few people could make tofu at this time in the Tang Dynasty.

Of course, there must be a way of tofu in the royal family. Recently, everyone doesn't eat tofu very much. Even if they are frugal, they don't eat tofu every day.

"It's recorded here that the beans can be made into soy milk, and you can drink it with sugar or salt. Then it's made into bean curd, and you can also add sugar, but you can also add other ingredients to make it salty."

"Wow, is this book the practice of all kinds of beans?" Li Lizhi said happily, "Aye Auntie, this book is really amazing, with this book, everyone can eat a variety of things, It's no longer in favor of cooking beans."

Li Shimin and Empress Changsun looked at the book in their daughter's hand and thought about what she had just said, and felt that what she said made sense.

Originally, I thought that these recipes were just bought to improve meals, but I didn’t expect that they would benefit the people. Unexpectedly, Li Shimin and Empress Changsun were very happy.
