What's softest in the world rushes and runs over what's hardest in the world. (2024) is a glimpse of queer families in Singapore, where LGBTQIA+ couples and their children are not recognized as legitimate by the state. Like Poh’s short film Kin (2021), What's softest is a hybrid documentary work that combines interview material with a constructed communal space for play and imagination. The film’s title is taken from Ursula K. Le Guin’s rendition of the “Dao De Jing,” referring specifically to the dichotomy between water and stone. Incorporating the sensibility and interdependence of the natural world and Eastern cosmology, the film presents queerhood as an open field of possibility, one brimming with life that is yet to come.
