Nanjing Road is the main shopping street in Shanghai. It is known the world over and is definitely a place you must visit if you go to Shanghai.
However, make sure that you visit at night because if not you will miss the wonderful neon lights and signs.
This corner is one of the most colorful, but it is not as colorful as it was in the past. You can see a picture of what it looked like years ago in my post Shanghai Nights. There is also a growing trend of digital screens replacing the traditional neon lights.
Advertising signs line each side of the pedestrian street and help light your way on a dark night.
In any case, there is a very high concentration of neon lights on Nanjing Road and your Shanghai experience is not complete without taking a walk down Nanjing Road at night.
