My Father Is a Big ShotEpisode 9

Lu Jianshe, who was once the richest man in the technology industry, became a security guard at the first factory he founded after retiring from public life. His son, Lu Zixuan, worked as an engineer in the factory. Lu Zixuan was unaware of his father's identity and had always held grudges against him. When Lu Zixuan invented the Beicheng No.1, Lu Jianshe came to attend the ribbon-cutting ceremony. However, he was ridiculed by the current factory manager and the workers. When the factory manager saw that Lu Jianshe took out his work permit with the number 001, he felt it was unbelievable and asked people to check it. Moreover, he believed that Lu Jianshe was pretending to be the chairman and thus suppressed him.
