Super School King Cantonese

On July 1, 2043, the crime lord General (played by Lu Huiguang) was arrested, and a week later, the iron-willed judge Yu Tiexiong (played by Zhang Weijian) presided over the trial. The General dispatched his mafia henchman Jian (played by Zheng Yijian) to return 50 years to find Tiexiong and brainwash him to render him incapable of conducting the trial. After the government became aware of this, they sent the Special Police Feilong (played by Liu Dehua), Broom Head (played by Zhang Xueyou), and Star (played by Ren Dahua) back to 1993 to protect Tiexiong. At that time, Daxiong was a long-term repeating student at a middle school in '93, often bullied and beaten by classmate Yu Jianan (played by Xu Zhian), with only his girlfriend Cai Ni (played by Yang Caini) being genuinely supportive. The three special police officers infiltrated the school, with Broom Head becoming a teacher, Tiexiong posing as Daxiong's classmate, and Star acting as Daxiong's sidekick, helping him defeat Jianan and extract information about Tiexiong's whereabouts. However, Daxiong claimed that there was no one by the name of Tiexiong in the school. Meanwhile, Jian also disguised himself as a teacher to infiltrate the school, and on the other hand, Daxiong's mother was planning to remarry Richard Yu... Will the special police succeed in their mission?
