Thunderstorm makes full use of the "three unifications". The story of eight characters from two families in just one day involves past grievances, and it is still confusing. In the narrow stage, it not only highlights the contradiction between ethics and class, but also highlights the strong disharmony between individuals and the environment and the times, and completes the characterization in various fierce conflicts. In fact, tragedy has long been lurking in every line and every foreshadowing, and it only broke out at the last minute, turning into a downpour, which shocked everyone's soul extremely strongly.
