    I once bought the beautiful bracelet from a store and felt excited when I tried it on. Sadly, I was soon disappointed at that my naughty kids broke it. But instead of just feel sad, I chose to repair it myself.

    To my greatly surprise, it didn't take a long time to do it. As time went by, I found that I was not happy with just repairing my breaking bracelets. I started making new bracelets out the materials from my old one. Later on, I  begin to design on my own

    Then I made my first deal. Back in 2013, I posted my bracelets on WeChat for the first time and several friends said that they wanted it. That was just the start. With much materials at hand, I made my designs into reality.

    This winter holiday my classmates and I go to the Sunshine Welfare House for voluntary work. After we went there, we talked about how we could do for the kids over the phone. The next day, we arrived at there with gifts we had prepared, and we received a warmly welcome. Then we began to play with them. I drew picture with the older kids, and my classmates told stories to the young ones. We spent the whole afternoon with them, talked and laughing. It was getting late. We waved goodbye to him and felt delighted to able to accompany those children.
