Why do Turkish people use ''güle güle'' instead of just ''bye''?

Turkish people use the phrase ''güle güle'' instead of just ''bye'' because it is a more polite and formal way of saying goodbye. The phrase literally translates to ''smile, smile'' or ''smilingly, smilingly'' and is used to wish the person well on their journey or after their departure. It is often used in situations where one is not likely to see the other person for a while or when saying goodbye to someone who is older or in a position of authority.

Güle güle is a part of Turkish culture and etiquette, and using it shows respect and kindness to the other person. It is also a way of acknowledging the person's presence and wishing them happiness as they go about their day. Using this phrase can make a good impression on Turkish people, and it is always appreciated when non-native speakers use it correctly.
