in March 27, 2017, Ji'nan, Yin Yanli, 71 years old, still engaged in machine embroidery. When I was 14 years old, I fell in love with embroidery for the first time, and I had been in love for 57 years in a blink of an eye. As an apprentice of Wang Yuzhen, one of the founders of Ji'nan machine embroidery, Yin Yanli is eager to pass on this skill, so that more people can learn and understand machine embroidery.
