How do you spell suicide in Chinese?

Chinese, unlike Western languages like English, French, and German, does not have an alphabet. Instead, it has something known as a "character system" that is composed of thousands of different symbols (known as characters) that each have a different pronunciation. So, rather than spelling, Chinese write characters. The Chinese Word for "suicide" is 自殺. This is pronounced "zi4sha1" in Hanyu Pinyin and "tzyhsha" in Gwoyeu Romatzyh.
