now let me say something about beijing opera. beijing opera is very popular in china. it has a history of more than 200 years. during the reign of the qianlong emperor in the qing dynasty, qianlong had a interest in the local opera. in 1790, to celebrate his eightieth birthday, he summoned opera troupes from different places to perform for him in beijing. four famous troupes from anhui province remained in beijing after the celebration. in 1828, a hubei troupe came to beijing and often performed together with the anhui troupes. the two types of singing mixed together and gradually a new type came into being known as beijing opera. now is the performance. i hope you will like it.
