As it is named after the Gouba Conference, a lesser-known yet historically pivotal meeting, which laid the foundation for victory on the Red Army's Long March, the elementary school has a tradition of highlighting its revolutionary culture and history. The five students designed two lessons, both concerning the village's Red heritage. The program has been filmed to make a documentary.

As the "protagonist" in the documentary's first episode, Xu serves as the lecturer of a public lesson, which is themed around Liu Hulan, a revolutionary martyr who sacrificed her life at a young age.

Explaining that the connection between Liu and the movie 1921 is "youth"-because the delegates to the CPC's first national congress had an average age of 28 as depicted in the film-Xu says he hopes the lesson will encourage the children to believe that "everything is possible when you are young" and bravely pursue their dreams.
