This unusual event building appeared early in my Miao Ying campaign, but after more than 100 turns the event related to it, still remains to be triggered. 

Frustratingly, at one point the event (A wine to die for) actually did trigger, but a game crash forced me to reset to the previous turn so the progress was lost.  After this reset the event has never triggered - I'm not sure whether this might be related.

Either way, the event triggering either seems to be bugged, or the chance for the event to happen is absurdly low.
