In a minority village in Sichuan province, three siblings live with their elderly grandmother. The introverted and understanding sister and the naughty and stubborn brother need to take care of their younger sister, while their parents go out to work away from home and return home only a few times a year. "Em Chu Em Nie Zi Bo" is about the daily conflicts between the brother and the elder sister in this family. The older sister silently takes care of the youngest in the family and is often angry at the brother for not learning, while the younger brother is very rebellious to his sister's discipline and often comes home with injuries from the fights. They participate in an audition for the choir. Because if they are selected, they will be able to go to Shenzhen to meet with their parents. The siblings begin to understand each other and sing their hearts out.
