Sweet potato. Fan, preach "Fan".

Xiao Min Ji by Zhou Lianggong in Qing Dynasty? Sweet potato: "In Wanli, Fujian people can plant foreign land and barren gravel land."

In the past, sweet potato, which shared the fate with poor land and wild weeds, was the staple food for farmers to spend the famine relief. Nowadays, with the prosperity of the days, ordinary people have also lived a well-off life. Sweet potato is no longer the staple food of villagers, but has become coarse grains for pigs and cattle. With the rise of dietary health culture, sweet potatoes, which were originally ignored by villagers, have become the favorite of citizens. The fluctuation of sweet potato value reflects not only the change of eating habits, but also the change of the times.
