Through the 1980s and early 1990s Ho created a series of martial arts films made with a "cut-and-paste" technique, which means they were created with the help of splicing various unrelated material (including the recurring motif of ninja-themed scenes, often with little or no connection with the already disjointed plot) and dubbed together. Several of the films' titles are an amalgamation of the word "Ninja" and the title of an already existing movie, for example, "The Ninja Force", "Ninja The Protector", "Full Metal Ninja", and "Ninja Terminator". He would film footage for one micro-budget picture, and then edit and splice the shots together in a different order, adding in footage from the various obscure or unreleased HK, Thai, Filipino and other Asian movies (martial arts films, crime films, comedies, etc.) to fill the gaps, and then dubbing over the result to create a final product. This allowed him to create several Z movies with the budget of one, though it is often difficult to discern how much of the finished product was actually filmed by his crew.
