Every early morning, an 69-year-old elderly man from Misishi Alley Community in Hangzhou takes the early shift of K151 electric car to a simple residence under the overpass in the northern city. A plate hangs there -- Gao's Camera Museum Appraisal Department. The private camera museum was established and managed by the old man. It opens at 8:00 am every day. The old man has been collecting cameras for 50 years and has guarded the museum alone for 18 years. The name of this old man is Jisheng Gao!
