I lived and worked on the HKUST campus in the 90's.. Very picturesque. Surrounding coastline very rugged. He picked a good spot. No egress there at the bottom of the hill. Fun fact: He camped just below the historic location of Shaw Studios, who popularized the Kung Fu movie genre
I lived in HK in the 90's at the HK University of Science and Technology. It's out in the New Territories, surrounded by small villages and otherwise mostly undeveloped dense, low-lying scrub. We'd hike in the country parks and it could be surreal; Remnants of abandoned villages like in the article. Feral dogs like in the article. We had some Hakka ladies take us on their boat out to I think it was Pak Sha Chau where there was a small pathetic abandoned amusement park. Also there was a larger island with an original refugee camp from the Vietnamese boat people era. Now I think it is a golf course.. Great memories
