Although Peng Minling and her husband Liu Kai are often extremely busy with their work as immigration police officers, they have never lost focus on the education and guidance of their two daughters.

Huanggang Port inspection station, where 41-year-old Peng is stationed, serves as the core hub connecting Shenzhen and Hong Kong. The daily inspection volume here is astonishing, with passenger flow exceeding 110 million since 2024. Every weekend and holiday, the port is always crowded with people, which is also the busiest time for Peng and her colleagues.

Being good at drawing, she realized that vivid comics might be an excellent bridge to popularize customs clearance policies and showcase the demeanor of immigration officers. She has created a series of comics for inbound and outbound passengers to refer to.

Her husband Liu, 44, is a backbone member of the information technology department of the Shenzhen border inspection general station. The products he participated in researching and developing have obtained national patents, making positive contributions to "strengthening police with technology" and creating a safer and smoother customs clearance environment.

He shoulders the responsibility of coordinating the technical operation and maintenance of all ports in Shenzhen and eastern Guangdong."System stability is crucial to the smooth flow of the national border,"Peng said, which means he must be on call 24 hours a day. Once emergencies such as power outages, server crashes, or line failures occur at the port, he must rush to the scene first regardless of day or night.

Years of working side by side have long forged a tacit understanding between Peng and Liu that requires no words. When Liu is called to rush to the maintenance site at 3 am, he doesn't need to explain; when Peng returns home at 11 pm or quietly goes out at 5 am, she also doesn't need to say much.

They married in 2009, and with the birth of their two lovely daughters, this dual-police family was filled with even more laughter.

The special nature of a dual-police family means that companionship is often "absent". During winter and summer vacations, when children of the same age travel with their parents, their daughters often have to stay at home. Although they occasionally feel envious, the sensible children have long understood that "mom and dad have important tasks".

New Year's Eve reunion is often "remote" in this family. When the duty schedule requires both husband and wife to be on duty, a special "video New Year's Eve dinner" has become a tradition — Peng at the brightly lit port, Liu at the duty site with flashing equipment, and the children at home with their grandparents. The three parties briefly meet through the screen. In just over 20 minutes, there are a few greetings and a few laughs.

However, no matter how busy they are with work, the couple has never relaxed in the education and guidance of their two daughters. They often take their daughters to the port, or encourage them to put on volunteer uniforms to experience their parents' work in person on weekends or holidays. Watching their parents being busy in police uniforms with a heroic posture, a sense of pride arises spontaneously in the children's hearts.

Peng believes that the best education is silent infiltration. She hopes that the seeds of helping others can germinate and grow naturally in her daughters' young hearts.

Regarding the future for their daughters, the couple has an open and firm expectation: there is no need to set a specific career path, but they hope that the children will delve into their chosen fields and pursue excellence.
