Well, if Nicholas Tse starts chasing Wu Jing, who is chasing Philip Ng, sets out from near the Western Market in Sheung Wan, the chase soon moves a few miles to Kowloon West and then finishes another couple of miles away, as the trio jump from the roof of Kowloon City Market on to the roof of Kowloon City Elderly Health Centre.
I actually just stumbled across this, whilst walking from Diamond Hill to Tsim Sha Tsui, having previously thought that it would probably be over in Kowloon West, like the rest of the rooftop chase...
