On April 8, Xinya College organized a group of faculty and students to watch the play Copenhagen at the National Theatre of China with the support of the platform for aesthetic education, "Drama Arts Hall" (Juyiting). Written by British playwright Michael Frayn in 1998, the play won both the Pulitzer Prize and the Tony Award, and was immediately translated into multiple languages and staged around the world. Since director Wang Xiaoying brought the play to the stage of the National Theatre of China in 2003, it has become a classic in the domestic theater scene.

The play Copenhagen tells a story based on real historical events. Its core focus is not on restoring historical truth, but on exploring the moral responsibilities of scientists and the dilemmas of human nature. The story revolves around a mysterious meeting in Copenhagen, Denmark, in 1941. The visitor was German physicist Werner Heisenberg, and his host was Danish physicist Niels Bohr. Bohr's wife, Margrethe Bohr, was also present. After this brief meeting, the two completely severed their ties. Since they belonged to opposing camps and the content of their conversation was highly sensitive, the true purpose of Heisenberg's visit became known as the "Copenhagen Mystery," a famous enigma in the history of science.

In the play, all three main characters are already deceased. Their souls reunite in heaven, where they repeatedly recall, reconstruct, and reenact that pivotal conversation. At the core of the play is the ultimate question that constantly haunts Heisenberg's inner mind, also known as the "Heisenberg Question": "Can a physicist with a moral conscience engage in research on the practical explosive applications of atomic energy?"

Heisenberg's dilemma is that as a scientist, he was eager to solve the puzzle of nuclear fission; as a German, he was filled with patriotic fervor; but upon realizing that his research might lead to devastating consequences, he was burdened by heavy moral shackles. The play does not provide an answer, but rather fully presents this pain and struggle to the audience.
