This unrelated mother and son live in Bijie City, Guizhou Province. Since July this year, Ma Xiao has filmed her and Xixi's daily life and posted it online. In just two months, she has sucked millions of powder.

They live in a big ravine in Bijie, Guizhou. They are warm to each other and live a poor but happy life. People watching them can't help sighing, sad for their miserable life and deeply moved by their mutual protection.
