I reg'd heung.cn too. it's not pinyin, I knew that when I reg'd it. I think it's Cantonese...the type of Chinese they speak in HK. It's a name, first, last, boy, girl... but not very popular in china. There is a skyscraper and a village in HK with the name though.
I think .cn is a good place to invest. There are more than 13m domains in .cn. That's really a lot! About the same as all ngtld combined...
