I am in the courtyard, animals are just vegetables!

"Grandma, we're here to see you!" the two children shouted as they entered their mother-in-law's house.

This is what their mother Song Xianxian taught them. They have to speak loudly otherwise grandma won’t be able to hear them.

"Here they are, my eldest grandson and granddaughter are here, come in quickly, they don't need to change their shoes." The mother-in-law was very happy to see the two children.

"It's snowing outside. Your shoes are dirty. If you have their slippers, change into them. Tingting, Yangyang, daddy will get some food for grandma. Let's go to the living room and wait for daddy first, okay?"

"good!"

There was still a month before the Chinese New Year, and Cao Dongfang took a lot of food again, enough to eat before the Chinese New Year, and he would take again around the 27th day of the lunar year.

Before the Chinese New Year, some were sent to my father-in-law, Song Xianxian's elder brother, and uncle-in-law.

During the Chinese New Year, everyone needs to have food and clothes.

.......

"Where are Lanlan and Song Qianguo?"

"They both accompany the child to sleep, but the child is still fussy and difficult to take care of before and after feeding at night, and the child likes to cry.

Cry for no reason! Not as easy to take care of as Tingting and Yangyang. At night, they have to play for half an hour after feeding before going to sleep, and they have to keep the lights on!

"My sister is not well behaved and it's not good to cry. Daddy said so." Tingting said in a baby voice what Cao Dongfang taught them.

"No!" My son is just a follower when it comes to talking.

"Hahaha, she's not as well behaved as Tingting and Yangyang when they were little. That child might be a girl. She cries a lot. She'll be better when she grows up!"

"Lanlan should go to work soon, what should I do?"

"Why go to work? Just like you, I took a year off. Lanlan and Qianguo can't rest well at night. This child drinks milk and pees separately.

How can you rest well if you have to drink milk, cry four or five times in one night and keep the lights on?

"Song Qianguo and Lanlan are not good. They are like this with just one child. I have no problem with two children, but you can't even handle one. Bad review." Song Xianxian said proudly.

"You're not giving me a bad review. You won't be exhausted without Dongfang at home. The child is taken care of by Dongfang. What does it have to do with you?" said the mother-in-law contemptuously.

"How can it not matter? I have to breastfeed the baby every night!" When Song Xianxian heard this, she felt that her contribution was gone and she quit.

"Besides breastfeeding, what else do you do? Isn't it Dongfang who is doing it?"

"My breastfeeding is also a credit, a great credit. Dongfang doesn't know how to do it." Song Xianxian was very shameless.

"Haha, Song Xianxian, you are so shameless. You made me laugh. Which man would breastfeed? Tell me."

"I won't argue with you about this. I have made great contributions and you are being unreasonable." Song Xianxian refused to admit her mistake.

.......

"Song Qianguo, Lanlan, you two are not capable enough. You can't even take care of a daughter. Do you need your sister's help?" Song Xianxian said with a smile.

"No need, it will be fine in a few days. It's normal for my daughter to cry a little!" Song Qianguo spoke listlessly.

Mo Jinlan, "Duoduo, the main problem is that it's not good to turn on the light at night. Once the light is on, people can't rest well!"

"Just don't let her turn on the light. It will be fine in a few days. This is a bad habit!"

"It's annoying to hear someone crying. Try it when you're a few months older!"

"Look, the child is asleep, let's eat! Mom and my second sister-in-law are going to prepare the meal!"

"There is very little salt in food nowadays. If you eat too much salt, nothing will taste good."

"After three months, it will be better, and after half a year, it will be better. These dishes have less salt, and it is better than drinking porridge and eating steamed bread."

"That's right. I'll endure it for another month!"

"Drink some juice. I got the juicer. Fruit is good to eat!"

“I drink it too, but when it comes to juice, I’m more of a casual drinker!”

"Let's eat and clear away the unused items on the table!" Mother-in-law came out with the food.

.......

When they returned home in the afternoon, Cao Dongfang and Song Xianxian walked home with their two children.

It had been snowing outside for quite some time, and there was a layer of snow on the ground, which had little effect on Cao Dongfang.

It had an impact on Song Xianxian and her two children. The road was slippery and the two children walked unsteadily. They fell a few times and then started to walk properly.

It was a snowy day, there was snow on the ground, and the child didn't run, so it didn't hurt when he fell.

I'm just a little dirty because of the snow. I'll go back and change my clothes!

"Dad, Dad, why is it snowing?" the daughter asked again.

“The reason why it snows is because it is cold now. When the temperature in the clouds is too low, the small water droplets in the clouds will freeze into ice crystals. When they fall to the ground and are still in the state of ice crystals, it is snowing.

Also, when snow and ice melt, they absorb heat, so the ground temperature will be lower than when it snows.

Snowflakes are mostly hexagonal in shape. The reason for the wide variety of patterns is that hexagonal molecules are the most common among ice molecules. For hexagonal flaky ice crystals, due to the different curvatures on their faces, edges and corners, they have correspondingly different saturated water vapor pressures. The saturated water vapor pressure on the corners is the largest, followed by the edges, and the smallest on the plane.

Under the same actual water vapor pressure, the saturated water vapor pressure of each part of the ice crystal is different, and the condensation growth is also different. For example, when the actual water vapor pressure is only greater than the saturated water vapor pressure of the plane, the water vapor condenses only on the surface, forming a columnar snowflake.

When the actual water vapor pressure is greater than the saturated water vapor pressure at the edge, condensation will occur on both the edge and the surface. Since the speed of condensation is also related to the curvature, condensation is faster in places with large curvature, so condensation is faster on the edge of the ice crystal than on the surface, forming more flake-shaped snowflakes.

When the actual water vapor pressure is greater than the saturated water vapor pressure at the corners, although water vapor condenses on the surface, edges, and corners, the sharp corners are prominent. The water vapor supply is the most sufficient, and the condensation grows fastest, so branch-shaped or star-shaped snowflakes are mostly formed.

In addition, the ice crystals are constantly moving, and the temperature and humidity conditions in which they are located are constantly changing. This causes the growth rates of different parts of the ice crystals to be inconsistent, forming a variety of snowflakes.

Tingting, Yangyang may not understand. All he needs to know is that it snows in winter and it rains in summer when it is hot.

When you grow up and go to school, your teacher will tell you! "

"The clouds are cold and it's snowing. I got it, Dad!" The daughter is still very smart.

......

"Dongfang, there's not enough snow today, otherwise it would be nice to make a snowman."

"Heavy snow falls here every year. We can make snowmen and have snowball fights when the snow falls."

"I liked it when I was a kid, but now that I'm older I don't like it anymore. I think snowball fights were more fun when I was a kid!"

"Dad, what is a snowball fight?"

“Ask mom what she liked when she was a child!”

"Mother!"

"It's about using the snow from the sky to roll a round snowball and throwing it at others.

It's snowing lightly today, so the snowballs you make will be covered in dirt and dirty. I'll take you guys to play with it when it snows heavily! "

"Mom, keep your word! Let's have a snowball fight!"

"Let's have snowball fight!" My son just follows me.

"Don't worry, Mom keeps her word!" Song Xianxian was happy to see that the two children were willing to play with her.

......

Time flies. At the end of the month, Cao Dongfang started to distribute benefits again. This is the first quarter's benefits, as everyone knows.

After delivering the papers at half past twelve, Cao Dongfang went home to eat.

Continue playing with the children in the afternoon.

"Dad, the things have been distributed. Let's eat and play in the afternoon!"

“Eat and play in the afternoon!”

......

Song Xianxian's idea of ​​taking the children to build snowmen and have snowball fights was realized on New Year's Day.

There was moderate snow all night on the day before New Year's Day, and it stopped snowing at eight in the morning.

Song Xianxian also has some time, so she takes a rest today, and she didn't forget the two children.

After breakfast at 8:30 in the morning, Cao Jiajia cleaned up, while Cao Dongfang and Song Xianxian took Tingting and Yangyang out.

Song Xianxian first took the two children to make a snowman, and with the help of Cao Dongfang, they made rapid progress.

“Mom, mom, this is the snowman, we got it, make it beautiful.”

"Put on a hat. These two are eyes, this is the nose, and this is the mouth. Mommy will tie this red scarf around the snowman's neck.

Tingting, Yangyang, do you think this snowman is pretty?" Song Xianxian asked her daughter and son.

"pretty!"

"nice!"

"Mom, mom, my brother and I are going to make a snowman too!"

"Okay, you guys build a snowman, mom will help you!"

"Mom is cold, her hands are cold!"

"Tingting, Yangyang is just like mom, rub your hands and they won't be cold anymore!"

“Okay, Mom!”
