Looking for a specialty store selling iron yam in Beijing is like looking for a needle in a haystack. Unless you can get advice and help from local people. In fact, you can buy iron bar yam online, which is sold in Taobao shop and iron bar group mall. The boss is from wen county, and wen county is the production base of authentic iron stick yam.

Pay attention to the place of origin when buying iron yam online. The delivery place must be Jiaozuo or Zhengzhou, otherwise it is not an authentic iron stick yam. What's more, it's summer, and Tieshan medicine is not easy to preserve. Buying dried iron yam slices is the most suitable and easy to store.
