Chapter 44

Having been spoiled by the two best products, Baitang didn't want to go out for a walk anymore and went straight home.The days are short in winter, but after four o'clock in the afternoon, the sky has already darkened.Baitang took a taxi back downstairs to his house, looked up and saw that the light in his house was already on, and Baitang's heart lightened accordingly.

"I'm back!" Baitang opened the door and saw Bai's father, mother and Wu Xuemei making dumplings at the dining table, while Xing Xiaokang was sitting by the coffee table doing homework.

"Are you eating dumplings today?" Baitang looked at the fat and white dumplings covered with half a curtain, and his saliva began to flood.

"Yes, mutton stuffing, you can eat it to your heart's content!" Bai Ma rolled out the dumpling wrappers. Although the Bai family are not from the north, they all like to eat pasta and often make some steamed buns, dumplings and noodles.I saw Ma Bai holding a small piece of dough and pressing it down gently. She held a rolling pin in her right hand, pressing more than half of the dough, and turned the rolling pin up and down. She held the unpressed dough in her left hand and kept turning it. Turn the dough while rolling.After a while, the dumpling wrappers, which are thin on the outside and bulging in the middle, are evenly rounded.

Papa Bai and Wu Xuemei were in charge of making the dumplings. Both of them were skilled hands. They put the stuffing in the center of the dumpling wrapper, folded the dumpling wrapper in half, squeezed it hard with the thumb and index finger, and the dumpling was done. It was so cute and chubby.

Baitang hurriedly washed his hands and sat next to Wu Xuemei, picked up a dumpling wrapper and began to wrap it: "How do you make mutton dumplings?"

"I went to buy mutton stew today, and I wanted to make dumplings, so I bought some more mutton to make mutton dumplings." Bai Ma said while rolling out the dough.

"Today is not the winter solstice!" Baitang said.Eating dumplings and drinking mutton soup is the custom of the winter solstice, right?Every year on the day of the winter solstice in the lunar calendar, dumplings are an essential festival meal, regardless of whether they are rich or poor.The proverb goes: "October [-]st, the winter solstice comes, and every family eats dumplings." This custom is said to be left in commemoration of the "medical sage" Zhang Zhongjing's winter solstice.

"Who said that you can't eat dumplings and drink mutton soup if it's not the winter solstice?" Bai Ma rolled her daughter's eyes, "Eating mutton often in cold winter can nourish qi and tonify deficiency, promote blood circulation, and enhance the ability to resist the cold; it can also protect the stomach wall and help digestion. In winter, we need to eat more mutton and drink more mutton soup. I also think about making mutton hot pot in two days, since I don’t like it, I don’t want to eat it.”

"How could you not like it! I like to eat mutton, I like to eat mutton very much!" Baitang hurriedly surrendered, with a flattering smile on his face.

"If you want to eat, pack it for me!" Bai Ma ordered her daughter to work.

"Yesmadam!" Baitang raised his hand and gave a nondescript military salute, making the other three adults laugh.

"Mom, I don't know one question." Xing Xiaokang held up the exercise book and asked her mother for help.

Her mother directly shirked responsibility: "Ask your aunt, she is a college student!"

College students also shirk responsibility: "Ask your grandpa, he is a university teacher!"

No one pushed Dad anymore, he washed his hands, and went to tutor the primary school students with their homework.

"Tangtang, are you free tomorrow?"

"Yes, what do you want to do?" Bai Tang asked.

"I'll buy the meat tomorrow, and we'll stuff sausages together!" Bai Ma said.

"Then why bother? Isn't there sausage filling in the market? You can't just fill it and bring it back."

"How can the ones irrigated outside be as clean and tasty as those irrigated at home?" Bai Ma turned to Wu Xuemei, "Xiaomei, are you irrigated with us or separately?"

"Let's go together!" Wu Xuemei laughed, "Anyway, I won't go back to my mother's house for Chinese New Year, Xiaokang and I will spend it with you."

"Okay, let's go buy meat together tomorrow. There are only two of you in your family, and five catties should be enough."

The three of them were talking, and after a while all the dumplings were wrapped, and Bai Ma went into the kitchen to boil water, "Wu Xuemei cleared the table and washed the dishes, Bai Tang went to Bai Pa and Xing Xiaokang, and went to see how her father, who was her teacher, was doing everything. Difficult grade school subject.

"Arrange 2004 squares in a row, and children A, B, and C take turns to color these squares in turn. Starting from the first one, A dyes one square red, B dyes two squares yellow, and C dyes three squares. Then A dyes 3 squares into red, B dyes 4 squares into yellow, and C dyes 5 squares into blue, until all the squares are dyed. Among them, they are dyed blue How many squares are there in total?"

"There is such a story in ancient Russia. A group of wild geese was flying, and another wild goose touched them and called: Hello! There are 100 geese. The leading wild goose replied: No, we are not 100. If we add more 100%, then add 50% of the original group, and then add 25% of the original group, and finally add you to 100. Tell me: how many do we have now?"

"The circumference of a circle is 1.26 meters. Two ants start from both ends of a diameter and crawl towards each other along the circumference. The two ants crawl 0.04 meters and 0.05 meters per second respectively, and each crawling 1 second, 3 seconds, 5 seconds Seconds... (continuous odd number), turn around and crawl. Then, when they meet, how many seconds have they been crawling?"

"Find the pattern: (1) 1, 3, 4, 7, 11, (), (); (2) 1, 2, 3, 6, 11, 20, (), (); (3) 7, 3 , 10, 3, 13, 3, (), () (4) 1, 2, 5, 13, 34, 89, (), () (5) Arithmetic sequence: 11, 14, 17, 20... What is the tolerance? What is the 15th item? What is the sum of the first 15 items? What is the number of items corresponding to the number 101?"

"..."

Baitang was overwhelmed: "I forked! Is this a third grade math problem?"

"This is a Mathematical Olympiad problem!" Primary Xing raised his head and said, with a look of frustration on his face, he didn't know any of these problems.

Baitang rubbed the child's head comfortingly: "Even junior high school students can't answer these Olympiad questions. You are only in the third grade of elementary school, so it won't be normal. Don't be depressed."

Bai Tang thought about the complaints on the Internet about parents' complaints about elementary school Mathematical Olympiad questions, and believed that these Mathematical Olympiad questions did not develop children's intelligence but tormented them: "The brain could be used to think about more other useful knowledge, but it is all used to focus on this. ”, “Both teachers and parents feel that the things in the textbooks are not enough, and they take pleasure in confusing the children.” The China Social Survey once conducted a survey and found that forcing children who are not strong in mathematical logic to learn Olympiad mathematics will destroy them. Normal thinking leads to psychological problems.

"The teacher stipulates that you must complete these questions?"

Xing Xiaokang shook his head.

"Then don't do it." Baitang said straightforwardly.

"But……"

Dad Bai also agreed with his daughter's opinion: "These questions are not something you can do now. Your teacher understands and won't make things difficult for you."

Dad Bai decided to ask Wu Xuemei to call the teacher and stop embarrassing the children with these questions.

"Are you all ready? It's time to eat!" Wu Xuemei walked out of the kitchen holding a large porcelain basin full of dumplings.

"Okay, okay!" Baitang answered while pulling the child up, "Let's go eat dumplings."
