I have English, Japanese and Chinese version. I bought the Chinese translation through bo2ke4lai2wang3lu4 shu1dian4 (internet bookshop) www.books.com.tw. The title is mao2 ze2dong1: xian1 wei2 ren2 zhi1 de gu4shi. The author Jung Chang herself made the translation. I hope this information will help.
Hope you've got the Chinese version already. If not, here's another online bookstore that sells it. You just have to guess your way through the check out process. If you click the English version of the website, you will be directed to the English version of the book.
