In late 2024, Zhang went viral online being labelled "Chinese Bladee".
On June 13, 2025, Jackzebra released the single "Givenchy," produced by evilgiane, elipropperr, and fleadiamonds, followed by a performance of the track on the popular online radio show On The Radar. He would also sign to internet rap collective and netlabel Surf Gang.
