Smart legislation makes Huangshan tea greener

Liu Xizhu from Huangshan, Anhui province, has been busy recently picking tea leaves in his tea garden that winds through the city's mountainous Yixian county.

First-time visitors may wonder at the thousands of very noticeable yellow plates that sit among the tea plants that cover the mountains.

"They are glue-trap plates that lure harmful insects away from the tea plants," said Liu. Every 1,000 square meters has about 60 such plates, provided by the local government for free.
