It's called a pseudo-documentary, but in fact, the film Lu Ban wanted to shoot was closer to the form of reportage literature.
Reportage literature combines novels and news, filling in the detail gaps with some literary means and artistic processing, aside from being factual.
Good reportage literature, while being true to reality, is also rich in emotion and touches the audience.
For such a work, Lu Ban felt, it would definitely convince people that these characters had really existed.
Lu Ban thought about it, he could find He Jiaoyang, but He Jiaoyang himself no longer knew about Nine Streams, and he guessed he didn't have contact information for anyone else.
And Tang Yu, whom he had met that day, must be a descendant of the Tang Family; since she was still inheriting the family business, she might have recollections or information about her predecessors.
However, Lu Ban hadn't added her WeChat and had no idea how to contact her.
