On a paper trail

It took him nearly three months and hundred attempts to get everything right.

Liu says that to create a complicated work requires logical thinking and plenty of mathematical calculations.

Liu became a full-time origami artist after he quit his job as a researcher at Renmin University in 2015.

Then, on April 19, 2017, Liu and a team set a Guinness world record by making a white paper rhino - 7.83 meters long and 4.06 meters high - in three hours and five minutes.

The effort was a call to the world to save endangered wildlife.

Liu is often referred to as China's top origami artist, or a Chinese origami master, but he says he is just an origami craftsman who seeks to deliver his ideas for the public good and spread Chinese culture through his craft.

On July 17, Liu was invited to the Capital Museum to teach high school students how to make hanfu, the traditional clothing of the Han people, from paper.

This was the third time he was at the museum on a teaching assignment.
