Fang Yuan, a second-year finance and law student, encountered an overseas fraud on his 200,000-yuan credit card. He did not panic and call the police, but standardized evidence collection and left traces throughout the process. With his solid legal knowledge, he strongly fought back against the bank's evasion of the violation and successfully received a compensation of 400,000. Later, when he was having dinner, he saw through the store's extortion tactics and defended his rights according to the law. He also exposed the hypocrisy of his classmate Liu Qiang who pretended to claim credit and owed money.
