Bāhé Academy was a guild hall for Cantonese opera practitioners. The original institution opened in 1889 to provide lodging and other services to opera troupes. It’s now a meeting place for retired artists. Bāhé is not open to the public, but you can see the original 3m-tall wooden door from 1889, the only item that survived a bombing by the Japanese in 1937. It was used during the Great Leap Forward as a parking plank for 4-tonne vehicles, and clearly survived that as well.
