"[In Chinese countryside] those who stay behind to continue farming constitute what is often called the "773861 army": "77" refers to the old (i.e., 77 years olds); "38" refers to women, typically married women ("38" is March 8, International Women's Day); and "61" refers to children (June I, International Children's Day)"
