She didn't cry or make trouble since she was a child, and she knew how to share housework when she grew up a little, Li Lan thought that her greatest luck in this life was to have this child.

"Sit down for a while, we'll be able to eat soon."

"Sister Lan, I'm here to help."

"No, it'll be fine soon, you can go and sit down."

Li Lan pushed Xing Lin out of the kitchen.

There was no way, so Xing Lin had no choice but to walk over to Li Xin and sit down.

Looking at the small one, I didn't expect the handwriting to be quite good.

Li Xin was stuck on a question, biting the tip of his pen and pondering.

"What's wrong, won't you do it?"

"Well, sister, how can we complete the course in the shortest time?"

Li Xin showed the title to Xing Lone.

Xing Xing looked at it and explained: "It is written here that there is no limit to the route, which means that you can run whichever way you want, but generally the detours are more tortuous, which will be more of a waste of time, excluding the third and fourth, we can see that the first and second distances are almost identical, if Xiao Xi wants to choose between these two roads, which one will he choose?" ”

"Huh?" Xiao Xin thought for a moment and said, "The first, because the second one still has a river, it will be a waste of time to cross the river." ”

"But it's also written that you can use tools, which means it takes you about three minutes to run through, but with rowing, it only takes one minute, so which way is faster?"

"Article 2." Xiao Xi said loudly.

Then I wrote it down in the notebook and analyzed the process one by one.

"Then sister, how do you write this summary?"

"Detours represent twists and turns, so don't take the wrong detours, be upright. Crossing the river with the help of tools means that you must learn to analyze details, be good at using things around you, have a heart that is good at discovering, and don't learn to be flexible. ”

"It's complicated, it feels so hard to understand."

Xing Xiao smiled: "You are still young, and you will understand when you grow up." ”

"Hmm."

"It's time to come over for dinner." Li Lan shouted.

Li Xin put away the homework book, walked to the dining table with Xing Lone, and the two went to wash their hands before sitting in their seats.

Smelling the fragrance, Xing Lin praised, "It's so fragrant, Sister Lan's craftsmanship is really good." ”

"Mom's cooking is delicious, sister, you have to eat more."

"Thank you, Xiaoxi, you have to eat more to grow taller."

"Okay, Xiao Xi has to grow taller."

"Haha, you kid, are you worried about height now?"

"There was a nice little girl in the class who didn't like to play with me, and she said I was too short." Li Xin said aggrievedly.

Li Lan smiled: "You! The little girl doesn't think you're too short, but she's afraid of playing with you and getting you. ”

"I'm so strong, how can I get hurt so easily?"

"That little Nothing can talk to her tomorrow and play together."

"I don't play with her anymore, I've found friends who like to play with me."

Li Lan shook her head helplessly, "The child's heart comes and goes quickly. ”

"Isn't that great? Happy. ”

"Yes, as long as Xiao Xiao is happy, I will be happy."

"Mom, can my sister come to pick me up from school tomorrow?"

"Why do you want Sister Xing Liang to pick you up?" Li Lan asked curiously.

"My new friend doesn't seem to have parents to pick him up, I want to invite him to the house tomorrow, and if my mother picks me up, he will be sad."

How can there be such a sensible child? It's so cute.

Xing Lin looked at Li Xin and thought with emotion: The child's feelings are really sincere and happy.
