I wouldnt put them much, seeing that the Chinese struggle with english, and the above words are pretty hard to spell anyways. Even a native english speaker would struggle with them
.cn names are currently increasingly used my manufacturers in China trying to target the US market. As the Chinese economy strengthens, hopefully the value of these domains will too.
I would say hold onto them. The Chinese are learning english very rapidly, especially since the Games are just around the corner. You could find a market for them around this time next year
