How do you evaluate "Tianshuqi Tan"?

The film was born out of an encounter with the BBC, and its creators were y influenced by the Czech education. It was a complete departure from the popularity of "tall and big" characters of the time, and it exuded a sense of humor in every aspect. There were no computerized special effects in those days, but I think the people were very serious and their ideas were bold and fresh. Unlike the highly decorative art styles of "Pandemonium" and "Nezha's Brain", "The Wonderful Book of Heaven" adopts a more delicate brushwork and heavy coloring art style, with the influence of the "Wu School" running throughout, including the immortal Yunmeng Mountain, the rainy and misty countryside of Jiangnan, and the magnificent streets of the bazaar, just as in "Riverside During the Ching Ming Dynasty", and so on. etc., creating a picturesque scene of ancient Jiangnan. Mr. Lou Ying-mei, the assistant cameraman, decided to use paint. The title of the film "Tianshuqi Tan" four words on the top, there is a large iron basin below the two colors of paint in it, through a solvent so that the paint slowly produce their own chemical reaction, the photographer and then gradually photographed, superimposed on the back of the four words. When the audience watches the movie, they see that the words don't move and the background moves, but they don't know how this special effect is done. This is the process of exploring the use of paint to show the rolling clouds in the sky, which was done decades ago by everyone, but back then there were no computerized special effects, it was all manual, requiring everyone to explore and innovate. When I think about it, this is also a kind of tenacity.
