My friend (Chinese) who lives in Nanchang, took my husband and I out here. She described this as "the Bund of Nanchang", modeled after the Bund in Shanghai. Part of the charm of the Bund in Shanghai's attraction is the colonial buildings that line it. Nanchang may not have the old architecture, but they captured the skyline of Nanchang across the Li River magnificently. All the buildings opposite are decorated with moving lights that to me represented the water that so dominates the landscape of JiangXi province. The fountain water show was the best part.
The water show lasts for a good hour or so, and the the water fountains and jets are set to the music with lights and the functions! You can actually see the crescendos of the music (various western and chinese songs) in the effects displayed. It's also enormous, with huge spouts and long long alleys. It's gorgeous, and very popular with locals who come out as couples, groups, or just young people on roller blades. Good for a wander around of maybe an hour or two.
There is also a fun fair carnival type area with rides that cater to the very young or the very adventurous. We didn't go on them, but it would be a welcome addition for a family. There are also food stalls. We didn't eat at them as we were so full from the Chinese hospitality they were showing us earlier, but you could definitely grab a snack here. There are toilets as well. Using a wheelchair might be difficult in some areas, but once you're there it's pretty flat, so good for those with mobility issues. (As compared to some other places.)
Recommend for a night out with anyone!
