Bell Tower Introduction: The theater building is flanked by the Bell Tower and the Drum Tower. There are four hollies in the front yard, of which the two against the wall are French hollies and the two on both sides of the flower bed are native hollies. There are two sweet-scented osmanthus trees in front of the east and west wings of the front yard. Every year around the 15th day of the eighth lunar month, the trees full of sweet-scented osmanthus fill the entire courtyard with fragrance.
