After graduating from Lu Yunfei Customs School, my father took me to Hongshankou Customs, where the cock crow can be heard in four countries. According to Yun Fei's plan, he stayed in Xiamen directly, and his girlfriend and future parents-in-law arranged a job for him. But arm ao however thigh, Yun Fei was Torre leng to HongShanKou. Dad Lu Tianting is the deputy customs chief of Hongshankou Customs. He arranged his son in Hongshankou, because Hongshankou is the birthplace of Yun Fei and because there is the spirit of Yun Fei's mother here. More importantly, dad wants to exercise his son in a difficult environment.

People are really trained in a tough environment. Due to altitude sickness, Yun Fei came to Hongshankou on the same day. Coupled with Torre's ubiquitous and strict self-discipline eyes, Yun Fei wants to quit completely. If Uncle Guan Changlan didn't pay attention to the "detour" strategy, Yun Fei really wanted to take off his clothes and leave. Slightly stable mood, Yun Fei is on duty. A few days after going to work, Yun Fei took it out on his roommate Xia Wei because his girlfriend broke up politely. After a fight with Xia Wei, he left angrily.

Yun Fei ran away angrily, which really broke dad's heart. Torre catch up, throw Yun Fei's luggage on the side of the road, turned back to the customs. After leaving Hongshankou, Yun Fei met his eldest brother Liu Jinshan in a small town. Brother Jinshan's father was also a customs officer of Hongshankou Customs before his death. He once carried out an anti-smuggling mission and died gloriously to protect the current customs Commissioner Lan Shu. In recent years, Jinshan has been in and out of Xinjiang and Pakistan, selling clothes and doing some foreign trade business, making a lot of money.

Under the guidance of Jinshan, Yun Fei returned to Hongshanguan and devoted himself to his work. Where did Yun Fei know that Jinshan used Yun Fei to smuggle Tibetan antelope cashmere through customs? If it hadn't been reported by an informant from Pakistan, Hongshanguan didn't know that someone had let the smuggler go. The blue tube commander received the information and deployed forces to step up the anti-smuggling inspection. Yun Fei thought of Jinshan's abnormal behavior and Xia Wei, who was on duty to protect his glorious sacrifice, and decided to use his rest time to test Jinshan. As a result, he reluctantly discovered that Jinshan was the suspect of smuggling Tibetan antelope cashmere.

Revealing his true colors, Jinshan and his accomplices held Yun Fei hostage. When Yun Fei was taken to the border by Jinshan and his partners, Jinshan died of infighting. Lu Tianting received a threatening phone call from a smuggler and immediately went to intercept it. Not far from the boundary pillar, Lu Tianting stopped the smuggler and cooperated tacitly with his son Yun Fei, resulting in the smuggler's death. After these life-and-death exercises, Yun Fei finally understood his father's painstaking efforts, determined to take root in the frontier, cultivate delicate flowers of love, and began his life journey.
