en qué localizaciones rodaron cuatro bodas y un funeral

Qu opera wailing was a form of performance in rural funerals. In rural areas, when someone died, the Wailing Woman would organize a eulogy and sing some sad songs to express the memory and grief of the deceased. The crying spirit girl was usually dressed in white mourning clothes, holding a microphone, kneeling in front of the mourning hall and crying, singing the paragraph "December Crying Father and Mother". This kind of performance was especially common in the remote mountainous areas of northwest Henan. The content of the performance was not limited to Henan opera and Qu opera, and sometimes it would be accompanied by a little Hui accent. The wailing usually lasted for about half an hour, and the host would give the wailer a red packet as a reward. As a unique art form, wailing still had an important cultural heritage value.
