Who is Han Fei-tzu from Xenocide and what is their importance?

Commonly regarded as the greatest of the godspoken on the Planet of Path, Fei-tzu truly is a great man. Having lost his wife when their daughter, Qing-jao (or "Gloriously Bright") was just 4 years old, Han Fei-tzu grants her her dying wish in spite of his own doubt and raises the child according to the principles of "The Path." Han is described as a good father, who is wise, compassionate, and an excellent example to his daughter.
