How was that long shot at the beginning of the movie "Ballad of Cloud Water" shot?

There are as many as 60 shots processed by digital special effects in "Ballad of Cloud Water", and the 6-minute long shot that shocked Oliver Stone was shot to completely outline the folklore of Taiwan in the 1940s and set the background of the era. Director Yin Li shot eight shots that maximized the scenes unique to Taiwan at the time: traditional Minnan opera, Taiwanese burlesque, local marriages, street vendors, and Kuomintang soldiers....... Several shots went up and through the sky, to group them together into a coherent long shot.

"This is unimaginable in a movie with traditional live-action footage, but Cloud Water Ballad skillfully uses digital technology to connect them without leaving a trace." Facing the questions of famous directors at home and abroad, director Yin Li laughed and said, "We froze with the traditional means of millet plus rifles to make the effects created by people's airplanes and cannons. Finally, the post-production of special effects processing, so that the original eight shots seamlessly synthesized a six-minute long shot."
