I definitely will come back. I only had 3 days to stay in this city for my business trip. Had half day to view this place.
It's not enough for me to go around to see entire city. However, I recommend if you would like to go this place, and maybe you need to spend 3 - 4 days to stay here. You won't be disappointed.
Yangzhou is not western at all but very Chinese. As they say in Yangzhou : "If you want to see China visit Yangzhou".
