The Hong Kong MTR ticket is very similar with the ticket in Shanghai. The difference is, it is much more expensive (9 HKD to go across the Victoria Strait v.s 2 RMB to cross Hong Pu River in Shanghai).
The Hong Kong Metro is colorful.
Hong Kong is famous as a crowded city, but the metro was built with large scale. There are very big halls undergrand, many wide tunnels and enough elevators. I didn’t experienced jam (short delay due to too many people) there.
I like the transition of the Metro most. From KCR to Central, I can always get to another line on the opposite side of the same platform as I get off. It is like Singapore. Shanghai and Beijing are different stories.
P.S. I am on business trip these days. I travel to a city, sometimes a county, sit down and have meeting with local customer, get on to a van, travel, and then sit down with another group of customers. I visit two places every day and sleep in a different city every day until this Friday.
