Go with the SLR. When I went there, a few people's rooms were sitting quietly beside three lanes and seven alleys at 6:00 p.m. without tickets. I didn't need to go to the rooms one by one to see the books I visited when I was a child. All the memories of Bingxin's grandmother's life came out, and Lin Jueming's most famous book with his wife was vomiting blood when she read it. Don't think about being lucky enough to walk into an old house.
