About the title of "Harry Potter and the Half-Blood Prince" it's Chinese Spelling...

I saw "Hali Bote - Hunxue wangzi de beipan" this title first time, I thought it's French. Then I read it slowly, I realized that's Chinese prounciation. I think it more appropriate to use the origional title. My mother language is Chinese, but I couldn't recognize it. If it's necessary to use Chinese, could it use Traditional Chinese? That would be great...
