On a business trip to Lanzhou, I walked around the pedestrian street, visited the waterwheel park, looked at the museum, and reported to my father. My father told me to visit the Eighth Route Army Memorial Hall. I went to the Internet to find two places. One was the Memorial Hall, the other was the former office. This is the Memorial Hall. There are some exhibits on display. Many things about the Eighth Route Army were introduced. I don't really understand this. I took pictures and went back to my dad to see it. It was a patriotic education in Lanzhou. I spent a long time in it. There were also various scenes of the Eighth Route Army's residence. It felt like it was in a TV theater.
