This work is presented in the form of a documentary, through shooting and interviewing the characters' work and life, and is carried out with the ups and downs of the characters' fate and their respective life choices, aiming to tell the rural story under the background of the new era. On the theme, this work attempts to convey the values of "little people" and highlight the traditional rural characteristics. In daily life, "little people" may not be eye-catching, but it cannot be denied that "little people" also have their own persistence. In this context, this work will be the most familiar people around as the main shooting object, namely the author's grandfather and primary school teacher. Grandpa is a prison office director. After retiring, he still wears a police uniform every day, is upright and helpful, and always sticks to his police heart. Teacher Yin, a rural teacher, used his spare time to test the drone driver's license, and used drone irrigation technology to solve the growth problem of 100 acres of rice fields, and reduced the pressure of farming for the rural elderly on his own. Even though the work is very busy, I still insist on guarding this village in my own way to help my neighbors get rid of poverty and become rich.
