Isn't it rather easy for Ziyi to prove her innocence.....

by opening the book and disclose to general public the details of her charity account? like the list of donors, how much money each of them has donated or pledged to donate, and how she has allocated those money to the benefit of earthquake victims?

An readily verifiable account book can easily corroborate Ziyi's supposed rectitude and salvage her already tarnished reputation. But curiously she chooses to withhold such a crucial piece of info in the face of growing public outrage at her alleged scandal, at her own peril. (not only is her career at stake here, she may be subject to legal liability)

If Ziyi has indeed managed the money she raised at fundraiser(s) held in the name of earthquake victims with due honesty and diligence, what is there to hide?
