The other day, one of my students asked me about the future of Hong Kong, after 20 years of handover, from a Feng Shui perspective, so I took out a satellite map of the Pearl River Delta Region of which Hong Kong is located at the end of the same Dragon Vein embracing the region and said to him.
It is very obvious to me looking at the map, the greater Mingtang or the ideal Xue (FS Spot) is located to the south of the city of Guangzhou, thus in the long run, the prosperity of the region will shift north-west-ward from Hong Kong. This was not possible before the handover because Mainland politics have cut off the regional connection through Human Qi, but now the political situation has changed and the region is opening up and consequently the Earth Qi will re-exert its influence aided by the human desire to make the region into one big basin.
The shift will start with Shenzhen and it is already happening now, this shift is mirrored with Macao to Zhuhai on the White Tiger side, but Hong Kong will never die out because it is located on the Azure Dragon, the Yang side of the Four Animals model and she will continue to play an active part, but not the only part in the region any more.
That was the answer I gave my student with this map shown below.
