So Hing Keung's photographs are full of humor. He is trying to bridge the Taoist idea of reincarnation and recycle together with the act of ChouDu (超渡), which means aiding the idling or loitering spirits to detach their grudges and ultimately step into the tunnel of reincarnation by an act, or a ritual.
In Mr. So photographs, the non-decomposed garbages found in somewhere were "detached" with the "offerings", suggesting the non-decomposed garbages also have grudges, if we didn't dispose them befittingly. Injecting the Taoist idea into the environmental issue is quite clever.
