Deng Chao plays the role of a radio host in the movie Passing Through Your World. Litchi, a policewoman played by Bai Baihe, is hearty, sincere and has a sense of justice. Mao, who likes to invent but always gets into trouble, attracted her attention. Litchi often runs after Mao all over the street. Litchi fell in love with Mao, and then boldly pursued it to show her love. This adds a lot of joy to telling the judge about it and to each other's lives.

Chen Mo, played by Deng Chao, is a radio DJ with autism, immature personality and extroversion. Although I help my audience and my brothers to solve their troubles every day, I am actually the most confused and lonely one. He doesn't say or express. Facing the reality, he wrapped himself in all kinds of armor and covered his heart with poverty, meanness, nonsense and broken cans. Because of the need of the role, Deng Chao exercised, dieted and lost weight before shooting, and lost weight in only 15 days 10 kg. Deng Chao is an opera fan, who loves to ponder the theater. Before filming the rain scene, he must soak in the rain for a while to find his own feeling.

Under the line that chicken soup overflows just right, the film ingeniously adds Zhang's favorite Chongqing scenery, the small church in front of the rolling mountains and the stone steps up and down the hillside, which is not only a different kind of scenery, but also brings a pleasant audio-visual experience. Zhang's most powerful medicine is the hero and soul figure in Home Front. Deng Chao interpreted this complex role well. His humor and profundity coexist, and he can switch freely between the two levels of polarization. The two emotional relationships and two identities in the film are also quite in place.
