Chen Lan went from being a university professor to being a free nanny at her son's house, working hard and without complaint for twenty years. When her granddaughter returned from studying abroad, she scolded her in German in public. Chen Lan responded with a Berlin accent, took off her apron and left home. She took out the black card left by her husband, checked into a hotel, and asked a lawyer to take back the property, freeze the account, and revoke her granddaughter's scholarship. Only then did the son's family realize that everything was supported by Chen Lan's money. The son knelt down and begged for mercy, but Chen Lan did not look back. The daughter-in-law is crazy, and the granddaughter starts by washing dishes and pays back step by step. The pomegranate tree blooms every year, and some accounts cannot be settled with money.
