His other works included Winds and Clouds in Public Housing, Wily Little One, Little Tough Guy, Great Dictator, Lau-keung the Contractor, The Invisible Weird Guest and Wonder Dog.

In 1977, Hei Po was closed and Ma joined Golden Comics, where he began employing realism in his works, such as The Five Brothers, which caught the attention of others in the industry.

The following year, Ma attended a one-year course at the Hong Kong Academy of Fine Arts to improve his drawing skills.

He quit Golden Comics and joined Ching Po, where he produced numerous works, including: Evil Experiment, Assault 13, Alien, I Wanna be Woman, Small Luk's Fight at Wudang and the Eve of the Battle, Martial House, Sword and Spear, Destroyer, My Pursuit, Great Stealer 13, Knowing You, Mad Dog, Security Guard, Story of Big-Nose Boy, Hillfire, and Five Affairs.

In Ma's career, his drawings were heavily influenced by the works of Ryoichi Ikegami for his realistic style and attention to details.
