How did Jan Hus continue spreading his ideas while living in the Bohemian countryside?

When Jan Hus left Prague in 1412 to spare the city from a papal interdict, he continued to spread his reformist ideas through two primary methods:

• Literary Activity: During his two-year exile in the Bohemian countryside, Hus engaged in "feverish" writing. He produced numerous polemical treatises in both Latin and Czech to defend his positions against his critics, including his most significant work, De ecclesia (The Church). He also wrote a collection of sermons titled Postilla and various religious tracts, such as Vyklad viery, desatera a patere, which became classics of Czech literature.12
• Preaching and Advocacy: Beyond his writing, Hus traveled and preached throughout the Bohemian countryside, which helped him significantly enlarge his following. His doctrines were further popularized by members of the lower Czech clergy, who disseminated his teachings to the masses.3

Through these efforts, Hus maintained his influence and continued to advocate for church reform, including the supremacy of biblical authority, even while living in exile in the castles of his friends.123
