Sweet Persian language is as old as history and the language of the people of Iran and other Persian-speaking countries such as Tajikistan. It is the language of Hafez, Saadi, Molavi and Ferdowsi, who are the greatest poets in the world. So far, I have taught many people who are interested in this language and now I have many friends in the world. The Persian language is sugar. Saadi says: Human beings are members of a whole In creation of one essence and soul If one member is afflicted with pain Other members uneasy will remain If you've no sympathy for human pain The name of human you cannot retain
