The director specially invited many retired soldiers when shooting this work, so almost all the actors in the TV series are retired soldiers. When watching TV series, you should find that the actors in this work are in great shape, because they often exercise in their daily lives. Some of these frequent figures are veterans, and some are from sports schools or martial arts schools. Almost all of them have military experience, so the image of a general can be very obvious.
When shooting a TV series, the director will ask the actors to fully integrate into their roles as far as possible, and at the same time, before the development, they will also take these leading actors to a place for a month-long special training and action arrangement. It takes a very long time to shoot a work for 9 months, plus one month's training in advance, so the actors actually paid a lot for this work. The director's high demands on the actors shape the high quality of the whole work, so in the end this TV series will be recognized by so many people.
The actors have made great efforts to interpret the image of soldiers in their works, which is the result of their infinite efforts. The main characters repeated this scene many times when shooting underwater rescue, and it was shot in a relatively cold environment. In order to achieve the best results, actors need to walk around in various places and also need to carry out various trainings. It can be seen that every picture of this TV series is very attentive, which can also reflect the director's high requirements.
