While there he taught Italian in a local school, then visited Constantinople briefly but had to leave because of plague outbreaks. He went next to Moldavia, where he spent a year tutoring for a wealthy Ghica family. By 1782 he had saved enough money to make a trip to Halle, Germany, where he enrolled in a university to study physics and philosophy. During this time he composed and published his autobiography, a manifesto for his intended educational program titled "Pismo Haralampiju" (1783), and the moral advice book "Sovjeti zdravago razuma" (Counsels of Common Sense, 1784). The morals book advocated co-education for boys and girls.
