In the Line of Duty 5: Middle Man - Three Fathoms Cove
Three Fathoms Cove in Tai Po District doubling for Korea. The final duel between Cynthia Khan and Kim Maree Penn takes place at Kei Ling Ha Hoi Pier which has been furnished with some fake walls and a roof. The orange lifesavers still seem to be the same ones. Kei Ling Ha Hoi Pier was also used as a platform for battle in My Young Auntie and Stage Door Johnny.
