In folk culture, the deer is a familiar animal, often seen as a symbol of strength, goodness and luck.
Images of the deer often appear in Vietnamese architectural media, especially in communal houses, temples and architectural works of historical value.
The Deer God painting is painted under the layers, guiding the light source surrounding Thay Quoc Oai Pagoda, where everyone gathers goodness and peace, becoming a mascot associated with many good things in life.
