Which domestic spy drama have you watched more than once? Why was it so attractive?

In recent years, there have been many spy dramas in the country. I have watched some of them more than once, such as Red, Secret War, Infernal Affairs, etc. These shows are very magical because they reveal the complexity of human nature and the difficulty of spy missions. The reason why a spy drama could be so attractive was that it revealed the good and evil in human nature, showed the complicated relationships and struggles between the characters, and also had some unforgettable plots and character creation. For example, the protagonists in " Red " did not hesitate to sacrifice themselves for the sake of national rejuvenation. This noble spirit was touching. Secret Warfare, on the other hand, revealed the complexity of political conspiracies and power struggles through the struggle between the two teams. Spy dramas usually had very thrilling scenes such as chases, escape rooms, explosions, and so on. These elements could bring great tension and excitement to the audience. In short, there were many spy dramas in the country, each with its own characteristics and charm. The audience could choose a drama that suited them according to their preferences.
