I was born in a small county ranked eighteenth in the region, branded as a first-level poverty county by the state. When times were good, my parents together could only earn about 10,000 yuan a year. Their expenses each year would easily run into several thousand. Our family only had one self-built flat, which was worth around 20,000 at the time, and we only had savings of two or three thousand that we dared not withdraw. We rarely had a proper meal with meat in a month. How do you calculate parents who dedicated their entire lives to support two college students?
