The First World War was one of the "modern" wars and had such a scale and destruction, which any other war could not boast. People who lived at that time suffered from depression.
Some people believed that the wave of suicides was caused by popular Hungarian song in 1933 called "Gloomy Sunday". To remedy the situation, the Hungarian government has created a "club of smiles."
So they wanted to turn the "city of suicides" in the "City of Smiles".
There was opened a school where the residents of Budapest have been taught how to properly smile
They used a special facial tape, which helped to learn how to smile.
