The acquaintance and love between Long Shengyue and Zhang Lanqian is used as the overt thread, and Long Shengyue's pursuit of statistical reform and determination to do something as a hidden thread are intertwined into a trilogy of love and career - youth is spring, saying love is not easy, and a clerk becomes a director. The love, emotional turmoil and return of true love vividly reflect the image of contemporary young civil servants who yearn for true love and are dedicated to their jobs. Long Shengyue's emotional changes from simplicity to complexity, and his subsequent efforts to become the director of statistics, alternately interpreted too many surprises.
