The rope is thin, round, tightly knotted, and heavy, with uniform size. The color is smooth, and the local specialty is Wurun. The aroma is high and pure, and the taste is strong and mellow. The soup color is bright yellow green. Natural pearl tea is made from fresh tea leaves with one bud, two or three leaves, or one bud, four or five leaves, all of which have longer buds and leaves. The history has been very long. As far back as over a thousand years ago, Pingshui Tea District included more than ten counties and cities in Zhejiang Province, Shaoxing, Shengxian, Xiaoshan, Zhuji, Tiantai, Fenghua, etc. The mountains within the area are intertwined, with dense and undulating peaks, shrouded in clouds and mist, crisscrossing streams, and a mild climate, making it suitable for tea production.
