Bamboo is kind of trees that attached with my childhood. I and my friends played selling and buying game together under the shadow of bamboo. Or someday we collected its leaves to fire in the winter. And I will never forget the moment that in the summer, we skipped nap in noon, and gathered near bamboo to enjoy the wind when it was really hot and no fan. Now everything is changing. No bamboo, everything in the past exist in our memory.
