Yodim Chenpi was founded in Xinhui Nantan Dao (The Nantan island), Nantan is located at the Southern-west of Huicheng, a place where three rivers (Tan Jiang, Pearl river and Nantanhai) meet. This place has four distinct seasons, fertile and organic soil, and good drainage. The soil also provides sufficient nutrients and enough moisture for the healthy growth of the hesperidium, making sure to have good taste and nutrition. Nantan Dao, Xinhui produces a rounded and big size of hesperidium, with a small seed and thick peel. It also comes with a rich in 油包 (the black dots on the inner side of the hesperidium, a place for the hesperidium saving the volatile oil (a good way to distinguish between real and fake hesperidium peel, more number of evenly distributed dots means better peel.) . In china, there's a proverbial, ' 东甲为多！南坦为佳！' (There's a large amount of hesperidium in Dongjia (The Eastern), but the best quality of hesperidium in Nantan (The Southern).), indicated that the quality variety of the Nantan-Chenpi in Xinhui has been recorded since time immemorial.

By investigating the actual orchard in Nantan, Yodim Chenpi has learnt the method and technology of planting the hesperidium there. We planted the top-grade hesperidium with the soil at the self-owned orchard in Nantan. Moreover, we did everything from the roots and made sure things we are saling are first-class products.
