Jinjing is the name of my town. There is a central park called ShiBiHu 石壁湖, which means The Lake of Rocky Wall.
Look at the photo above, there is such a rocky wall behind me and my students. What is special about it? It was used as a giant blackboard by the local scholars, mainly local teachers, to educate the Jinjing people about a new democratic revolution 100 years ago.
They used limewash and huge brushes to write slogans on this eall, such as: democracy, science, freedom, etc. These modern new words inspired more and more local youth to fight against the old system, and began to see a much wider horizon.
