Yu An opened Douyin and found the video that his friend Aite had a few days ago, "That's the video @an". When he clicked on it, he found that it was a few boys playing ball. The comments below were all asking for Jiang Che's Douyin account. The first comment was that the author Aite created an account named jc. Yu An thought of his friend's words, clicked on jc's account, followed it decisively and sent the first private message - "How to find the value range of a in the second question of the last math question"...
(Jc: Are you okay?)
Concept: A sweet story about youth campus
