The 19th Asian Games released the second film in its trilogy on Sunday, showing the comprehensive infrastructure upgrades within the host cities and how technology provides a smart experience for fans.

The film, Asian Games GO Hangzhou, utilizes the concept of a cellphone screen to highlight the natural beauty of Hangzhou and establish it as a smart city.

A stop-motion animation with decorative paper-cuttings, the film highlights the upgrade program for the Games.

The third and final film in the trilogy, Asian Games In Hangzhou, will use traditional Chinese stamp art to display the brand and legacy of the Games. It will be released in the near future.

The first short film, Asian Games SHOW Hangzhou, is a stop-motion animation using Hangzhou silk. It was released earlier this month.

The film — using individual frames embroidered on a thousand individual pieces of Hangzhou silk, each with exquisite patterns, designs and colors — creates an illusion of movement between frames. It tells the story of Hangzhou's sports heritage through a journey of traditional and emerging sports and culture, from diving and sailing to break dancing and esports.

In 2009, Chinese paper-cutting was added to UNESCO's Representative List of the Intangible Cultural Heritage of Humanity.
