From shan law : What are the pros and cons of using green screen and CG to mock-up a city compared with using props ?

From Jiaxin李嘉欣 LI : How to deal with the things, such as the furniture, after filming the movie?

From Song Yang, Stella : Thanks for sharing! Your talk gives me a chance to know  about what is behind a film. By the way, I want to ask what is most important to you in a realism film, the actors or the story itself?

From HuangXin @3035771294 : It seems that so many details have been noticed and changed. Is there any difficulty that you find hard to make it like Wuhan? Did you changed the dialects of all the actors and actresses?

From Li Yueshan May : is that really meaningful to create such ‘fake’ image of Wuhan? I mean I can understand such tiny image related to the collective memories, but … even if you film it in Shenzhen, the core idea of recording COVID19 and people would not change, this is another way ‘pretend’ it is Wuhan, right?

From Poon Ho Ting : How do you ensure every detail in the scene is just like the real one? Will you ask for comments from the locals in Wuhan?

From Chan Chi Lam : You mentioned before that your crew had to figure out the real medical environment in the hospital and ICU. How did you make sure that the information you got from research was accurate? Did you guys also asked some medical experts?

From Leung Kui Ming 4796, Sky : It is really inspiring to see how you mocking a city.. hardly can I recognize these place as part of Shen Zhen although I am living in it haha But I would like to ask what if people find out the truth that the film is not shot in Wuhan? Will it affect the ‘realistic atmosphere’ you are trying to build and affect the narrative of the film?

From Chan Chun Hing : Since creating a realism film, the movie should be as close as the reality. To achieve this goal, how important is the mock-up city compared to other aspects of the movie? (likes the poops, the dressing …)

From Chan Sum Kie Dorcas : Hi I saw another comment mentioning that some sets may not come to their attention when viewing a movie.  So when creating a city, which parts of detailed would you choose to recreate and which ones would you leave out in order to stay within the budget?  Thanks for your sharing
