"This is not a small sum. People from the CCAFC need to explain to us what happened," wrote a blogger with the screen name "zatanweiba."
"I will never donate my money to any charity organizations in the future," added "maizideniang."
In response to the criticism, the CCAFC publicly apologized on Tuesday, attributing the disputed cash flow to an accounting mistake regarding other monetary assets, and uploaded a statement detailing the movement of other monetary assets on its official website as evidence.
The foundation's full cash-flow statement, balance sheet and income statement, which may offer a clear explanation of its financial activities, however, are not available to the public.
Jiang Ying, a representative for the CCAFC, told Xinhua over the phone that a serious accounting mistake was to blame for the controversy.
