This is not an infringement. Huayi Brothers has not registered the name "If You Are the One"
As far as I know, the only registered movie name in the world is "Dragon Movie", and the copyright is Jin Yong bought it for CCTV for one dollar! Even so, the registration is only for the movie title industry.
If you want to open a restaurant called "Dragon Movie", no one will sue you!
What I know is that Hunan Satellite TV is going to sue Jiangsu Satellite TV.
Hunan Satellite TV believes that "If You Are the One" infringes the law and "is filing a complaint with the State Administration of Radio, Film and Television and other departments, and reserves the right to The right of the infringing party to resort to law",
This may exist, and it may be accepted by the court. The original poster, please search the copyright law on Baidu
