In Inner Mongolia, some experts have verified that Inner Mongolia is one of the cradles of oats, with a history of planting and eating for more than 2,000 years.

At present, the largest natural oat planting base in China is in Inner Mongolia-North Mongolia oat planting base.

Oats are widely planted in China, including Inner Mongolia, Hebei, Jilin and Shanxi. But in fact, most of them are planted in modern times, including pesticides, fertilizers and herbicides. This planting method can't be regarded as natural oats.

There are very few people like Mengbei who really don't use chemical fertilizers, pesticides and herbicides.
