🎨 Visual Imagery: Imagine a long 200-meter brick wall on a street called the Avenue of Eternal Peace near a very famous place, the Tiananmen Square. This isn't just any wall. It's like a bulletin board, filled with all sorts of writings – from personal emotions to grand political declarations!

👩‍🎓 Quick Summary: This wall became a canvas for public sentiments, especially against the government. Sometimes, authorities didn't like it and would shut it down. One brave soul, Wei Jingsheng, faced 18 years in prison for his outspoken criticisms. This spirit of seeking democracy led to what was known as "the democracy movement."

• Location: Avenue of Eternal Peace near Tiananmen Square.
