What is one of the most obvious differences between singing style in western opera and Peking opera?

One of the most obvious differences between singing style in Western opera and Peking opera lies in the use of vocal techniques. In Western opera, singers typically employ a full, resonant voice with a wide vocal range. The emphasis is on projecting the voice to fill the large opera houses. In contrast, Peking opera singers use a more nasal and falsetto-like voice that is focused on clear diction and expressiveness. The vocal style in Peking opera is also characterized by the use of vibrato, which is not commonly found in Western opera.
