There are instructions on Tianya community:

On the eve of Tudou's listing, ceo Wang Wei had a hard time, although his divorce from his ex-wife was over. But I didn't expect to be sued by my ex-wife at the critical moment of listing, demanding a new division of property. As for the dog blood feud between ceo Wang and his ex-wife Yang Lei, it is nothing more than family fortune's unfair trade, and the potato ceo did something when distributing family fortune, which made his company into debt, so his ex-wife was left at home.

Unexpectedly, shortly after Wang Wei and Yang Lei divorced, Tudou will go to Nasdaq. Wang Wei's ex-wife Yang Lei was very angry. On the eve of Tudou's listing, she sued Wang Wei to the court, demanding a new division of property.
