His grandfather Selim Rusi, supported him in continuing his studies in Bitola and later in Istanbul, where he met other figures of the Albanian National Awakening, including Ibrahim Temo and Dervish Hima.
At the end of June 1910, Shevket Turgut Pasha, who derided Langu as a “Latin priest,” crushed the rebellion, but it continued underground.
Langu continued to lobby for Albanian-language schooling in the area, and the people of Debar elected him unanimously as their first official teacher of same.
He was ushered into Elbasan by his longtime friend Aqif Pasha Elbasani and helped connect the tribes near Debar with the Provisional Government of Albania out of Vlorë.
A commission consisting of Langu, Elbasani, Tetova, Ismail Haki Peqini, and Ahmet Dakli, set out to professionalize local government in Debar.
