Summarize Chapter 7 in the book red scarf girl (absolutely no plagiarism!)

At the end of the alley, Ji-li notices a propaganda wall. One night, a counterrevolutionary is caught trying to scrape a da-zi-bao off the propaganda wall. Six-Fingers (Red Guard in charge) and his friends get more meticulous after that. A poster announcing that Jia Hong-yu is coming to town. She's a famous Red Guard leader who will give them all a big report. At the meeting, Jia Hong-yu tells a story about meeting Chairman Mao: Everybody lined up for hours just to catch a glimpse of the guy, but it was worth it. Legend has it that seeing Mao makes you happy. When she's done with the story, there's not a dry eye in the house, and everyone chants, "Long live Chairman Mao!"Later, Ji-li watches from her window as Old Qian is forced to kneel on a sharp washboard for hours while the Red Guards empty out his house. Sure, Old Qian is an old grump, but he didn't do anything wrong-his biggest crime was not lending a Red Guard his bike. Ji-li feels really conflicted about Old Qian. He's a counterrevolutionary who deserves what's coming to him; on the other hand, though, he's just an old guy with a bike. Eventually, Old Qian faints from heatstroke and has to be carried back into the house. The next day, they find out An Yi's grandma jumped out the window and killed herself. Ji-li remembers her being harassed about her class status. To make matters worse, suicide is a crime in revolutionary China, so An Yi's family isn't even allowed to have a proper funeral.
