Unlike Western languages like French, German, and English, Chinese does not have an alphabet. Written Chinese doesn't have letters that spell out words. Instead, it has characters that represent the different words of the language. The character for "open" is 開. In Simplified Chinese this is written 开.
Chinese does not use letters... this question can not be answered. Chinese instead uses character-words and thus only old, traditional words can be used.
you don't SPELL words in Chinese Each has a different character instead of a group of letters. Haley in Chinese is 海利 (if your computer can show Chinese characters), pronounced as "hi-li". If you have to spell it, then it's spelled "hai li".
