Celebrating Vietnam Reunification Day with Symbols of Victory and Unity

A high-resolution 8K image celebrating Vietnam Reunification Day (April 30), featuring the Vietnamese national flag with vivid red and yellow colors waving proudly in the sky. In the background, silhouettes of heroic soldiers raising the flag, symbolizing victory. Integrate a modern luxury swimming pool with European-style design, illuminated with red and yellow lighting. A subtle silhouette of a tank (T-54 style) appears in the background to evoke historical memory. Include the bold text '30/4' in a prominent, modern font in the upper left or center of the image. Add the Poolex company logo subtly in the bottom right corner. Patriotic, majestic, warm lighting, professional yet celebratory tone.
