Dozens of audiences attended to each program. For special program “Preventive maintenance of Printing press” performed by Mr. Kawana from Komori Japan, almost 140 audiences got together in the room. Many people took notes because Mr. Kawana’s presentation was very realistic using with real used or replaced service parts. He sent such parts and samples of oil to audiences to feel real things. That was very persuasive for them. To reduce the loss by damaged press in printing factory, “Preventive maintenance” thinking touched the chord of Chinese printers.
