Strangers - John Simm (2018) - Lau Fau Shan, Yuen Long

David and Jonah's mysterious wife kept a small bolt hole out in the middle of nowhere. I'm not sure about the actual building used, but the build up to the scene was filmed with Jonah and Lau Chen arriving at the bus terminus in Lau Fau Shan followed by them walking through the village.
