Cultural Note

The surname 竇 is associated with historical figures, such as 竇融, a well-known politician and general in the Eastern Han dynasty, which reflects the significance of family lineage in Chinese culture.

Memory Tip

Imagine a 'dough' (sounds like 'dòu')nut with holes in it, symbolizing the sinuses. The character 竇 has a structure that resembles a 'hole' (the top part) and a 'foundation' (the bottom part), much like how sinuses create spaces within the facial structure.
