Ah, Zhongshan ^^
Thanks for the photos, Lain, I can remember also about there when I was in that city ^^
In fact, I really like it when it is night.
Did you see the famous bridge who is "lighted" on, by night?
I remember about a path, in the city, where man can see some buildings which are (for most of it), white color, and the design is not really chinese one.
I will try to upload some photos here if I find some
by the way.
If you get lost, one of the best advices is to look for some buildings close to your hotel, take some photos, then you can easily remember where you are and where you came from ^^
(but I'm pretty sure you already know it ^^)
