I congratulate these people for their semi-technical work and their manual labor. God bless them always.It's incredible how slave labor still exists today!!!!They all need masks. Fine particles are very dangerous.Very hard working People.Allah Ta'ala Inko Mehnato Ko Qubool Fermaye Aur Inko Sehat Tandursti De Amin Summa Amin.How much hard work goes into making the things that give us peace. Good, amazing.
