The so-called "yam vermicelli":

In addition, the so-called "yam vermicelli" is actually cassava vermicelli. Yuzhou is an important vermicelli production base in China, but the "sweet potato vermicelli" and "yam vermicelli" sold here are all made of corn starch and cassava starch. In a humble house in Zhang Cun, Shu Tong, Yuzhou, workers mixed a small amount of corn starch and cassava starch and shoveled them into a machine to make vermicelli.

In order to save money in the market, it is a common local production method to replace sweet potato starch with cassava starch. Sales staff told reporters that they can produce 5 tons of cassava fans every day, most of which are sold as sweet potato fans. The person in charge of Yuzhou Yuxin Flour Industry Co., Ltd. said, "I sent 18 tons yesterday".
