Farmers have to chisel rock to create hollows and fill them with soil for cultivating rice on the Dong Van rock plateau in the northern province of Ha Giang.
With a lot of efforts and labor, Mong ethnic minority people living in the Ma Pi Leng Mountain have grown their crops that way.
The Mong people have a proverb, “No mountain is higher than the knee of the Mong people,” meaning that they can overcome the hardship and challenges of Nature.
