Strangers - John Simm (2018) - Shum Wan Road, Wong Chuk Hang

Shum Wan Road pops up a couple of times in Episode 5. Initially of course it is used as the establishing shot for the private marina that Jonah went to whilst following David Chen, and these are the two top shots below (the "To's Boats" sign is a real one by the way).

However, we also see part of the same area again later when Jonah decides to find out the address of Kai Huang by going to the charter company and asking for an address. For this scene, one of the several boat and marine companies based along Shum Wan Road was used and turned into "Asian Riviera Charters". The map seems to get a bit confused here because even though the road is identified as Shum Wan Road, the actual address of the shipyard is #20 Po Chong Wan Road, so I am not sure where one starts and the other ends. Anyway, the real life company is called Shum Wan Marine.

Strangers - John Simm (2018) - Shum Wan Road and Po Chang Wan, Wong Chuk Hang

When David leaves the casino, Jonah jumps in a cab to follow him and this must have been the mother of all journeys because they both miraculously manage to travel about 50 miles east, over the sea, and back to Hong Kong Island. The location is supposed to be a marina in Macau where a gangster is keeping his boat. In reality the taxi stops on Shum Wan Road by the Po Chang Wan shipyards and Jonah goes through the first one to find David on one of the boats in dock. The buildings in the distance are part of a 'luxury' development on Ap Lei Chau called the Larvotto.

The building behind is a school: Victoria Shanghai Academy
