In order to get into the Bai Xianyong lecture, you have to purchase tickets to see the performance of “Dream of the Red Chamber” at CKS Memorial Hall, showing from the end of March to the beginning of April. After you purchase your tickets, you can reserve a spot for the lecture (it’s free). Bai Xianyong is one of Taiwan’s most famous authors and wrote the famous gay novel “Crystal Boys” (Niezi), which is about the gay life in New Park (now 228 Park).
Anyway, everything is being hosted by 雲門舞集, and you can get more info on their website (they have an English version too):
