"The ricefields' sweet smell promises a bumper year; Listen, how frogs' croaks please the ear!" goes a famous line by Song Dynasty poet Xin Qiji. Yet, in the eastern reaches of China, the once-common call of the Chinese Immaculate Treefrog has become rare.

In a bid to shine a spotlight on the plight of this endangered species, post-90s documentary filmmaker Wang Ningjing journeyed back to her Jiangsu province roots, one of the last habitats of the Chinese Immaculate Treefrog. Through her lens, she crafted a compelling short nature documentary, sparking fresh awareness of, and rekindling hope for, the conservation of this remarkable amphibian.
