When I was based in Shenzhen I had to fly one of those approaches once a month to keep my rating in date. Bring a training trip we could only do it at the crack of dawn and the procedural circuit was incredibly long and high. It was a real pain in the neck and the scenario around the checkerboard was wasted.
However medivacs at night gave one a fantastic view of Hong Kong with all the lights on. Should we pick up a Chinese National from a platform we were routed low level directly across Victoria Harbour, then between Lantou and the New Territories to the Pearl River and onwards to Guangzhou. They built a bridge across to Chep Lap Kok but it didn't seem to make any difference to our transit height.
Departing from Shenzhen and crossing Hong Kong outbound you could tell when you crossed the border between China and Hong Kong. The Neons changed from all red to another series of colours.
