Uncle Chen Jianjun brings the mobility-impaired grandmother to Mom's house, drops five hundred yuan and leaves. Late at night, grandmother actually sits up and takes out three gold bars to give to her granddaughter for safekeeping. After the other two gold bars are discovered by uncle, the family turns against each other over elderly care and property. But Mom can never bring herself to be ruthless, just because at sixteen her older brother had dropped out of school to work and pay for her studies. The adolescent who once paid for his younger sister's studies, why did he calculate gratitude into a lifelong debt? Five gold bars reflect this family's most real human nature.
