In Hangzhou, a 70 year old aunt, who spent three years in love with fashion, designed a new hundred leather shoes, and won a national patent.

How can these hundred leather shoes change?

Let's go and see.

Aunt Ding: just buy a couple of shoes. You can always change patterns for patterns.

This is Ding's three year's design achievement -- hundred leather shoes.

The dresses dressed up by Ding Ma told us that from childhood, she liked to dress up more than her peers.

Aunt Ding: I like to look at magazines like Ruili fashion. I liked reading before, and I like this kind of stuff very much after work.

Aunt Ding worked in the silk system in the early years, and her working environment also promoted her pursuit of beauty.

Because of the poor economy, she changed herself to dress up on the basis of thrift.

Aunt Ding: there are several friends who have dozens of pairs of shoes in their shoes rack. I said why so many new leather shoes are not put inside, they say they are tired of it.

Aunt Ding said that at that moment, a wonderful design idea appeared in her brain. When she got home, she picked up the brush, and thought of it day after day, until three years later, she got the patent certificate of the hundred leather shoes.

Lv Zhicheng, deputy director of the Hangzhou Intellectual Property Office: through our website search, this patent is real, and now it is effective. If we want to reflect the value of the patent, we must have partners, such as manufacturers of shoes.
