Liu Qiufeng said, the most valuable collection in his shop is this mechanical clock on which he spent 10RMB in a garbage collection station. He spent one month working on it, repairing, grinding, painting and aging treatment. The Chongqing Jiangling Instrument Plant made this clock in its small yield in 1980’s. The clock is precious as the copper sheet on it was punched integrally.

The first floor of the coffee shop is for customer reception, and the second floor is Liu’s studio, where all instruments and working tables are arranged for repair. He was working on repairs in the studio even amid the firecrackers of Spring Festival this year. “It’s all because I like it.” he said.
