Rear of the Hualien Guangfu Sugar Factory lies a little-known hidden gem called the Laseo Spring Ecological Park. The park features six natural springs; each maintains a pristine ecological environment. The clear turquoise spring water appears as if dyed by God, giving rise to Taiwan's endangered native aquatic plant—the small-flowered stone dragon tail (Erianthus wightianus subsp. formosanus). This astonishingly beautiful site is intertwined with an emotional Atayal indigenous myth. According to legend, the mythical bird Dourou has always protected the residents of the longitudinal valley but was injured by a hunter. Fortunately, the villagers of Laseo nursed the bird back to health. However, misfortunes later struck repeatedly—in droughts and plagues. In response, Dourou shed six tears that transformed into springs, selflessly saving the villagers and bringing generations of prosperity and happiness. Combining the natural beauty of an untouched ecosystem with Atayal myth, the Laseo Spring was voted Taiwan's Most Beautiful Hidden Gem in 2016. The first spring, refracting sunlight into different shades of blue, is nicknamed "Blue Tears," akin to Taiwan's version of Jiuzhaigou Valley. The sixth spring’s crystal-clear waters enable visitors to board motorless boats to clean algae while closely observing the small-flowered stone dragon tail, offering a magical floating adventure.
