the Beijing Local Taxation Bureau demanded a total of over 12 million yuan (US$1.85 million) from Beijing Fa Ke Cultural Development Ltd.
in unpaid taxes and fines.
Were they able to pay this?
Offers of donations poured in from Ai's fans across the world when the fine was announced.
Eventually an online loan campaign was initiated.
Were all the charges of the case dropped?
On 27 September, the court upheld the 2.4 million tax evasion fine.
So what happened to WeiWei after that court decision?
In October 2012, authorities revoked the license of Beijing Fa Ke Cultural Development Ltd.
