Top structural engineer Chen Yu turned down a major project to accompany his pregnant wife. When his wife Lin Wan was about to give birth, their doorway passage was blocked and obstructed by Jiang Man's vehicle, restricting passage. Chen Yu immediately called the police, enduring his back injury to escort his wife around to seek medical attention. Jiang Man refused to move the car and repeatedly provoked them. As a group president, Chen Yu used legal channels to gather evidence and verified that Jiang Man's husband Zhao Gang was involved in a 300 million economic crime. Jiang Man was arrested for property damage, and the two ultimately received severe legal punishment. Afterwards, Chen Yu used his professional expertise to build a lifeline passage warning education base, was hired as the chief compliance consultant for fire escape passages, and popularized safety knowledge to guard public safety.
