How was the long shot at the beginning of the film "Ballad of Water Clouds" filmed?

There are as many as 60 shots processed by digital special effects in The Tale of the Clouds, and this 6-minute long shot that shocked oliver stone is to completely outline the folk customs of Taiwan Province Province in the 1940s and set off the background of the times. Director Li Yin shot a total of eight shots, which contained the unique scenes of Taiwan Province Province at that time to the greatest extent: traditional Minnan opera, Taiwan Province puppet show, local marriage, street vendors, Kuomintang soldiers ... several shots went into the sky, and they should be combined into a coherent long shot.

"This is unimaginable in traditional real-life movies, but" Ballad of Water Clouds "skillfully connects them with digital technology, leaving no trace." In the face of questions from well-known directors at home and abroad, director Yin said, "We have made the effect of building aircraft cannons by traditional means of millet and rifles. Finally, the post-special effects processing was carried out, so that the original 8 shots were seamlessly synthesized into a 6-minute long shot. "
