Chinese languages

Can anyone help me? I am taking a class on World Religions and cannot seem to find a free internet site that will give phonetics (like the english dictionary does).

The words I am looking for pronunciations on:

1. Jen
2. Chun-Tzu
3. Li
4. Te
5. Wen

Thanks to anyone who can clarify!

1：真
2：纯子？？
3：理
4：德
5：文

2： Chun-Tzu
2：纯子？？

may be 2: 孫子 ？？
