On the eve of the Spring Festival in 2020, at two senior high schools with different teaching styles in Jinhe, Anhui Province, No.1 Senior High School and No.4 Senior High School, students in Grade Three were in full swing preparing for the college entrance examination, but each had his or her own troubles. Monitor Tian Wenwen's parents ran a shop in Wuhan all the year round, leaving her to live alone; top student Zhou Bowen's mother had to work hard to make ends meet for the whole family as his father had been decadent for years; Pan Xiaoxuan, a slow learner, lived a boarding life all the year round because of his parents' divorce; Wu Jiajun's mother had great ambitions for his son which brought him great pressures; Gao Mingyu, a poor student, had good grades, but he was distracted by taking care of his grandfather. The epidemic hit and changed everyone's life: Tian Wenwen had to live with her parents again, and the depressed emotions for many years gradually broke out; Zhou Bowen tried to help his father cheer up; Wu Jiajun wanted to take the arts colleges' admission exam, but was resolutely opposed by his mother; Gao Mingyu couldn't have online courses because of poverty... The outbreaks of the epidemic had kept Shi Aihua and Wang Benzhong, two principals with different personalities, busy. In order to ensure students' review for the college entrance examination, Wang Benzhong, the principal of No.1 Senior High School, ran the school with an iron fist and strict management. He even ate and lived with students to ensure their safety; Shi Aihua, the principal of No.4 Senior High School, updated the online teaching equipment, paid attention to students' psychological issues, raised the national flag live, and mobilized the enthusiasm of teachers and students; Director General Qin of the Education Bureau actively mobilized and deployed in advance to lead schools to tide over the epidemic smoothly.
