The escape of the beasts means both potential chaos in the streets of the city and exposing the magician to people who might be against magic.
"This film can be enjoyed even if you haven't read a single page of Harry Potter, or seen a single film," Fantastic Beasts' producer David Heyman says. "It's infused with her spirit, it's J.K. Rowling, it's her, but it works on its own."
Yates says Rowling has four more stories she wants to tell, and the next two films in the Fantastic Beasts series will probably come up in 2018 and 2020.
Yates and Heyman also hint that one of the most-loved Potter characters, Dumbledore, will appear in the next film.
Dumbledore is the principal of Hogwarts in the Harry Potter series, but back in 1926, he was just a teacher of transfiguration, with Newt as one of his favorite students in that school.
The Fantastic Beasts series will show a different Dumbledore, especially his sexual preference, which was implied in Rowling's previous works.
Showing the complexity of the characters is one of the features that run through all of Rowling's books.
A reason why people respond to Rowling's work the way they do is because they see themselves in her characters, says Heyman.
"You may have wonderful families, you may be in love, but we all at times feel alone, we all at times feel like we are outsiders. Her books celebrate outsiders."
Online comments suggest many Chinese are looking forward to the film.
"The 'no-maj' in Fantastic Beasts is the best gift from Rowling to us," Raymond KIDult remarks of the character Jacob who doesn't have magical powers but becomes Newt's friend. "When he is laughing and clapping his hands, jealously saying that he wants to be a wizard, isn't he speaking for us?"
"We are the muggles who never get the admission notice," another web-user, Yourenmofangwodelian, says.
