Once upon a time there was a circle. One day, he went to race against the square. Oh, how fast it ran. It had already left the square far behind. When it climbed onto the championship stage, it found that a corner of itself was missing. How embarrassing! From then on, he felt that he was very different in front of everyone, and no one followed him. The square stopped climbing with it, the triangle stopped having picnics with it, the rectangle stopped playing computer games with it, and the semicircle stopped playing "beach castle" with it... It was very sad. Thinking of the previous scenes of playing with everyone, it cried sadly. . So it made up its mind to find the missing corner, end the discrimination, indifference and ridicule of its partners, and recreate the full circle that attracted so much attention!

On the way to find corners

Yuanzheng is looking for corners aimlessly.

"Hey, isn't this Xiao Yuan? How did you become like this?"

Xiao Yuan took a closer look and saw that it was Grandma Dashu.

"Oh, Grandma Dashu, don't mention it. It's all my fault that I ran so fast in the marathon and lost such a corner. Now it's good, the square brother and the triangle sister ignore me. Alas !…No, I’m just about to find the lost horn.”

“Poor child!” Grandma Dashu said distressedly, “You have been in many dangers along the way, Qianxin. It's hard, but you have to be fully prepared. If you don't pay attention, danger will come."

"Thank you, grandma, I will pay attention," Yuan said gratefully.

Yuan continues on her journey. A snail without a shell came forward.

“Hey, little brother Yuan, how did you become like this?”

“Hey, it’s all my fault. I ran the marathon too fast and lost a corner on the road. I'm about to go look for it. "Hey, Brother Snail, what's wrong with you?"

"Don't mention it, because I was too careless and forgot to take the 'home' with me after sunbathing. I'm used to it." The snail said calmly, "You'd better not look for the horn. What happened just now shocked me. I accidentally fell off the cliff and luckily fell on a branch. Fate... No, I almost climbed onto the salt just now, otherwise I would have to peel off my skin again, so you'd better not go looking for any 'horns'!"

"No, Brother Snail, Don't try to persuade me, I will still find you no matter how dangerous it is."

"Hey, Brother Yuan, take care of yourself along the way!"

"Goodbye, too!" Wave goodbye to the snail.
