How to combine traditional cultural elements with posters skillfully?

It is generally understood that flowers representing folk culture are drawn on the display surface of posters, but it seems difficult to reflect the effect of traditional culture as a whole.

Suggestion: The composition of the whole poster can be designed as a representative symbol of national culture, such as buildings and front gatehouses. On this basis, text introduction and floral decoration can be interspersed.

Of course, the composition of the building is a bit old-fashioned, and folk scenery can also be used. Lines and colors don't need to be complicated, but they should be representative, or typical ethnic activity scenes, with lines faded, supplemented by words and flowers.
