After returning from Chenchen's grandmother's house, Li Liang and Chenchen took advantage of the fact that there were still a few days before the restaurant opened, and they stayed at home to do their summer vacation homework.

It's just that there is no general consensus among teachers on assigning summer homework, and there is no unified summer vacation homework question for sale in the world. For example, in Li Liang's class, the Chinese teacher asked the students to write a weekly diary every week, the English teacher asked everyone to copy all the texts they had learned in the school, and the homeroom teacher, Wang Na, a mathematics teacher, gave each of them a set of mimeographed test papers, which she printed with the school's hand-cranked mimeograph machine in her spare time.

The weekly memorization is easy to write, and the math test paper was completed in less than an hour, and the slow speed is to copy English texts. Li Liang writes quickly, Chenchen is not slow, and her academic performance is also good.

In the next few days, Li Liang went to the restaurant several times with Chen Chunhua, Chenchen and others. The speed of the masters was very fast, the well was dug, the house was covered with asbestos tiles, and the walls were painted with a layer of white lime. The floor of the house was also brushed with a thin layer of cement according to Li Liang's request, and the open space in front of the restaurant was hardened with stones, so that even if it rained, the mud would not be stepped on.

Chenchen's uncle, Chen Huahan, also applied to the power supply station through the brigade, took a wire to the restaurant, and installed a separate electricity meter.

Chen Chunhua entrusted the carpenters in her mother's village to order the doors and windows and eight rectangular tables. Originally, Chen Chunhua wanted to set four large round tables, but was persuaded by Li Liang.

In the future, the restaurant will mainly do the business of the drivers who go to the city in the surrounding counties and the truck drivers who come to the cement factory to pull the goods, and generally the number of people in each group will not be much, and if the large round table is customized, it is not suitable for two or three people to sit at a table, and it is estimated that the guests are not happy to sit at a table if they don't know each other.

Chen Chunhua listened to Li Liang's analysis and felt that it was very reasonable, so she ordered eight sets of rectangular tables that were not big or small. Generally, each table can seat four people, in case there are more than one person, you can also add two stools to seat six people per table. In addition, if there are many people, it is convenient to share a rectangular table.

In addition, a large sake vat was added to the restaurant to hold rice wine purchased from the village. In this era, the police department has not yet begun to investigate drunk driving, but drivers also know that drinking liquor is easy to cause accidents, so basically drinking one or two rice wine is the choice of most drivers.

Another serious problem is that the weather is hot, and vegetables, especially meat, are easy to spoil, so Li Liang asked Zhang Qingxiang to go to the chemical factory to buy a bag of potassium nitrate based on the experience of later generations. Potassium nitrate ice making has a very long history in China, according to historical records, at the end of the Tang Dynasty, people mined a large amount of saltpeter in the production of gunpowder, and people can make ice in the summer. Gradually there were people who bought and sold and added sugar to ice to attract customers. In the Song Dynasty, merchants also added fruit or juice to it. Merchants in the Yuan Dynasty even added fruit pulp and milk to ice, which was very similar to modern ice cream.

However, potassium nitrate is toxic and can be converted into nitro compounds to induce liver cancer, so it cannot be eaten directly. When you use it to make ice, you need to pour some water in a large basin, then put it in a small basin, pour a basin of water into the small basin, and then pour potassium nitrate into the large basin, and the water in the small basin will freeze.

Li Liang used the potassium nitrate bought by Zhang Qingxiang to do an experiment, put the meat he bought in a small basin of water, and after a while, it froze, and Zhang Qingxiang's family was stunned.

Chenchen saw it and asked Li Liang to make some popsicles. Li Liang used the white sugar at home, dissolved it with cool white culture, put it in a white porcelain cup and put it in a basin, and leaned on a small sharpened bamboo stick in each white porcelain cup, and after the sugar water in the porcelain cup was completely frozen, he could pinch the small bamboo stick and take it out to eat.

When everyone was eating it beautifully with sugar water popsicles in their hands, Li Liang's heart blossomed. In fact, as early as 1956, our country produced the first Snowflake brand refrigerator in BJ, but the refrigerator at that time was mainly used for medical treatment. It was not until 1983 that the Snow Refrigerator General Factory introduced the production equipment and technology of Philips in the Netherlands and launched a production line with an annual output of 50,000 medium-sized single-door household refrigerators. At that time, there was a shortage of household refrigerators in China, and snowflake refrigerators were loved by consumers for their stable performance, moderate price and low repair rate, and the products were in short supply.

There are also people selling popsicles on the street every day, and their popsicles are made from food factories using large ice machines. As a child, Li Liang often looked forward to popsicle sellers coming out of the stall, usually using insulated buckets to fill popsicles, or wrapping them in thick quilts outside foam boxes. Generally, the cheapest syrup popsicle is 2 cents a piece, and the cream and mung bean are 3-5 cents a piece. Sometimes if you're lucky enough to buy something that is about to melt, the stall owner may only charge you 1 cent.

"Li Liang, why are you so smart and know everything?" said Chenchen adoringly as he ate a popsicle.

"I used to read in the newspapers that some places use this method to make ice to cool off!" Li Liang explained.

"This is great, I'm worried that the ingredients will not be good to preserve in the future!" Chen Chunhua said with a smile, "But such a bag of potassium nitrate won't take long, Qingxiang, you can ask someone to buy two more bags in Ming'er!"

"Auntie, you don't have to buy it anymore!" Li Liang listened to Chen Chunhua's words and said, "This potassium nitrate can be recycled, use it to make ice, and when the ice is melted, you pour the water into the basin and put it in the sun to dry, and after the water dries, it will appear again and can be reused!"

"Yo, you can still use it like this! It's so convenient, it seems that I need to buy a few bigger pots to bring over!" Chen Chunhua said happily.

The next thing to do is to choose the name of the store and prepare the menu, ingredients, and condiments.

That night, Li Liang's family and Zhang Qingxiang's family got together and pondered what to choose the name of the store.

"How about the public restaurant?" said Li Liang's mother, Wang Xiujuan.

"Auntie, I think it's still called a people's restaurant. Zhang Junjie also joined in the fun and said one.

Zhang Qingxiang has no culture, so he thought of a "people's hotel".

Li Shuangzhu couldn't think of it, so he sat there and laughed.

Li Liang thought for a while: "I think it's a little better, how about Wangke come to the hotel?"

Everyone thought about it, "Wangke comes", Wangke comes into the store, and it is Wangke when he enters the store, this name is good! Everyone is no longer entangled, so they use this name.

Considering that in the early days of the restaurant, only Chen Chunhua and Zhang Meng, mother and son, were running the restaurant, and there were not many people, it was not appropriate to set up too complicated dishes. Therefore, the dishes are mainly set by Chen Chunhua, and the price of the dishes is combined with the current price of the state-owned hotel, and the appropriate reduction, and the final menu and price are determined, which makes Li Liang feel a lot of emotion, please see:

Boiled pork slices (1 yuan), braised pork (1 yuan), braised grass carp (1 yuan), stewed small trash fish (1 yuan), stir-fried meat with bamboo shoots (0.8 yuan), fried meat with fungus (0.8 yuan), fried meat with green peppers (0.8 yuan), scrambled eggs (0.5 yuan), fried vegetables (0.3 yuan)

Clear soup noodles (0.2 yuan), egg noodles/shredded meat noodles (0.3 yuan), rice (0.02 yuan/two grain stamps), rice wine (0.5 yuan/jin)

Li Liang thought that when this menu retired in the future, he must treasure it.
