Long Xiaoning, a female college student sent by Tsinghua University to temporarily teach in Ewenki Nationality Township, wanted to make a career here. However, Liu Bai, a male teacher who guided her teaching and shared her class, suddenly attracted her attention. Because the dormitory was bombed by students, Long Xiaoning had no choice but to move into the same dormitory with Liu Bai. The longer they got along, the more they discovered that Liu Bai was not only good-looking, but also kind-hearted. He wanted to use his knowledge and enthusiasm to dispel the haze of being unable to get ahead among the students in Nationality Township. The two of them worked together to save the dropouts, solicit sponsorship to expand the library, and guide the students who had just begun to love to embark on the road of hard work. The two also secretly fell in love. But Liu Bai has always been conflicted, not wanting Long Xiaoning to take root in the hard-working countryside like himself, so he has always concealed his identity as a senior at Tsinghua University. But when his identity was revealed by a student, Long Xiaoning was pleasantly surprised and strengthened his belief in staying here. He confessed his love hard and the two finally got together. But not long after, Liu Bai froze to death in the snow because he went to dissuade the students who fled into the snowy mountains. Long Xiaoning, carrying their ideals, insisted on training generations of students and became meritorious teachers. He did not reunite with his lover until his death.
