According to the map, many Tang-era writers traveled long distances, especially Li Bai, his footprints covering a significant part of today's China map.

The abundant poems and traveling experiences proved to be a treasure trove, but also brought difficulty to the production crew, as they had to choose five from a total of more than 2,000 poets of the Tang era.

"This is the documentary's first season. Just like you need to identify constellations to navigate when sailing at night, we wanted to find the brightest stars among Tang poets to navigate the documentary," Li Wenju says.

"A person's life has many stages, and in different life stages, the poets produced works on diverse themes, so we zoomed in on a representative journey they made to present a specific aspect of their lives."
