What is the most interesting play you have ever heard?

The most interesting thing should be "La Jing Ba" that I watched with my grandparents when I was in junior high school ... It was probably about an unfilial couple, who made a jingba out of thorns cut from the mountain and dragged an 80-year-old lady to the mountain and abandoned it. Then the couple's children didn't see their grandmother when they came back from school, asked their neighbors, and then went up the mountain to find her grandmother and pulled it back. When the children come back, ask the couple to put away this Beijing bus and pull it to the mountain when they are old.
