The long scar extends from his upper arm to the forearm, an indelible imprint, not only on his limb, but also on his career and in his mind.
At 3 am on June 17, 2015, Bi and his brigade went to a karaoke bar to detain a suspected drug trafficker, based on an anonymous tip. While taking the suspect away, eight people rushed out, blocking the way of the police car.
Facing the menacing gang holding stones and bricks, Bi showed his badge. Unexpectedly, they charged at him-later claiming that they didn't know they were police because the officers were wearing civilian clothes.
As the car pulled over, the brigade leapt into action. The police and the thugs clashed in what quickly descended into a chaotic scene. For a while, two policemen detained the suspect in the car, and three other policemen confronted the thugs outside the car. However, Bi soon realized that if the fight continued in a stalemate, the police will lose the advantage, the worst case being the suspect escaping-a most unfavorable scenario for clearing up the next case.
In the face of the villains' advance, Bi jumped at the right moment, scuffled with the gang leader, and pressed him to the ground. In the desperate confrontation, the thug resisted violently. Bi, who had been working on investigation for three consecutive days and nights, was extremely tired, and suddenly felt a sharp pain in his right arm as he struggled to suppress the thug.
It was only after the man was subdued that Bi discovered his right arm had been severely injured. At 5 am, Bi was taken to the hospital by his colleagues.
X-rays revealed the humerus of his right arm suffered a comminuted fracture. After a 6-hour operation, a 23-centimeter-long plate and 11 steel screws were permanently embedded in his right arm, accompanied by a blue disability certificate issued to the hero.
If it weren't for the injury, Bi would have traveled with his wife and enjoyed a long-awaited honeymoon.
In the eight years since his fledgling anti-drug career began, thrilling scenes of hero cops arresting bad guys in TV shows have been his daily reality. For him, fighting on the front line against drug crimes is always a matter of life and death.
The fight with a suspect in the drainage ditch of an expressway left him with multiple bruises on his body. Common occurrences are not limited to running through crowds and jumping railings to chase a drug trafficker, or fighting a suspect face-to-face with his bare hands against the blade of an opponent's knife.
When a drug dealer's vehicle tried to evade a roadblock, Bi broke the window, jumped into the car and grabbed the keys, leaving his forearms and hands cut and scratched by the shattered glass.
Anti-drug police usually cannot reveal their identities in public, and they often rush to the scene before they can give their family a heads-up of the predicament they might find themselves in.
In May 2020, when his wife was about to give birth, Bi was undertaking the most difficult and tiring investigation, following a suspect for five consecutive days and nights. The summer heat pierced his clothes, which were wet and sticky with the smell of stale sweat. In the end, he and his colleagues arrested the suspect and seized more than 20 kilograms of heroin on the spot.
