In an action scene, Ma Yue accidentally sprained his waist, but he still kept working despite his illness. After several scenes, he was sweating like a pig. Facing most close-ups, he has a big bag on one side of his nose. In order not to affect the image and delay the shooting, he designed some actions such as supporting his chin to solve this problem. In order to play the daughter of "spy" Tao Zeru, Li Man lost weight before shooting. On the set, Li Man often helps the staff to do things, and he remains patient even if he is not feeling well. Because filming is too hard, she is always troubled by dark circles, so "how to get rid of dark circles" has become a big topic for young actors in the cast of "Jiang Cheng Ling" after dinner. In a highlight in prison, Tao Zeru, Fan Ming and production director Lemon, who plays the villain "Luo Datou", give full play to the whole day's scenes. Although it took a little longer than expected, the final effect was beyond everyone's imagination. In Jiang Cheng Ling, Fan Ming's walking posture and action style were carefully designed by himself and then "recreated". As a pistachio, Fan Ming began to help others "find feelings" as long as he met actors, staff and even directors in the crew. In one scene, Gaowa Siqin was injured and unconscious in the hospital. During the filming, many fans wanted to take photos with her. She also specially arranged makeup for the mirror to show her respect for the fans. In Hengdian, due to the lack of suites, Gaowa Siqin volunteered to live in an ordinary room with her son. In order to overcome the shortcomings of the special drama "too cold", the screenwriter Anton especially strengthened his affection and love drama for the script.
