West Lake lotus root starch has a long reputation. In fact, most of the West Lake lotus root starch is not produced in the West Lake, but in Sanli Village. Lotus root production in three villages is related to its unique geographical location. The ancient Beijing-Hangzhou Canal passes through the village, and Yalan Port and Sancun Port are intertwined in the village. It is a good place to plant lotus roots because of its low terrain, little water and fertile soil. The lotus root of white crane, which is rich in the local area, has seven holes, fresh and tender meat, large lump, fine powder and high powder yield. It is a good product for making lotus root starch.
