In recent years, the natural world has been Huang Yuxin's chief subject matter. However, his works are not overly concerned with the artificial depiction of landscapes. The flowing water in his works symbolises the passage of time and life. Water, mist, and bubbles are metaphors for a realm where the eternal and the ephemeral can coexist. In The Lost Bubbles (Lot 119), the artist magnifies microscopic bubbles into an extreme proportion and colours them with vibrant hues. Such a magical but fleeting moment is frozen in this composition. Huang Yuxin's painting is also a record of the consciousness: "life is like steam, hastening or slowing, it never flows backward." These translucent bubbles emphasise the quietude of this frozen moment, as if they were paying respect to time itself. This moment of silence provides us with respite from the ever changing world.
