Facing the middle-aged crisis, the teacher, Piao Hongyuan, was appointed to take over a problematic junior class in senior 3. This class included students who were having puppy love, those who smoked and skipped classes, those who did not change after repeated education, those who drove a luxury car, those whose parents were divorced and left unattended, those who were children of migrant workers, and those who were poor and struggling to feed themselves. With his wisdom and love, Piao Hongyuan solved the confusion, perplexity and problems of teenagers, and led the whole class to create the miracle of college entrance examination. At the same time, he also solved his middle-aged crisis and ushered in the second spring of his career.
