Alternatively, "NHẢM XÁ" might be a different title. Let me double-check. "Nhảm" in Vietnamese means something like "trashy" or "b-movie," so maybe the full title is "Nhà Nhảm Xá" instead of "Tam Thiên Nhảm Xá." I found a few references where the title is listed as "Nhà Nhảm Xá" (Trick House) directed by Tô Văn Bảy. The user might have misspelled it as "Tam Thiên Nhảm Xá."
