You can enter for free with a valid certificate. Come to this old revolutionary area and see the traces left at the beginning. There is a statue of Mao Zedong De outside, or an adaptation of the monument. There are 6 floors of the high-degree ladder. You can see the feeling of the entire Sanwan when you climb up. There is a restaurant here, there is a dish called safflower, which I have not eaten before, a bit sweet. There is a souvenir selling around.
