Lin Xing kindly helped his distant cousin's family who came to Beijing to work hard. He helped them open a food shop, promote and attract traffic, and often gave away unused items. But one time when he was shopping for groceries, because his mobile phone was out of battery and he still had 30 cents left to pay, his cousin's family surrounded him and criticized him in public. They took out his account book and counted the green onions, ginger, and garlic that he had given him, and took advantage of him. The cousin's family intensified their efforts and took malicious revenge after the business declined. They sent pictures of wreaths and anonymously reported secrets in an attempt to destroy Lin Xing's work. Lin Xing, who couldn't bear it anymore, set up a trap to expose the truth. However, his cousin's family ran into trouble one after another due to lack of money and trouble. In the end, he suffered the consequences and returned to his hometown in despair.
