According to Fox 8, Xiaoli cried uncontrollably in the cinema and began hyperventilating and trouble in breathing. She was taken to a hospital where she was administered oxygen to normalise breathing.
"I saw that the patient had been breathing heavily, and according to the description from her peers, her crying caused hyperventilation. We immediately gave her oxygen and relaxed her emotions by appeasement, reducing her hyperventilation symptoms," The International News quoted a doctor as saying.
Directed by Anthony and Joe Russo, "Avengers: Endgame" stars Robert Downey Jr, Chris Evans, Mark Ruffalo and Chris Hemsworth, among others.
