Early the next morning, Feng Qingxue rode her bicycle into the city by herself to exchange Grain Tickets with Old Mrs. Cao.
A ten-kilo and a five-kilo flour Grain Tickets were exchanged for a bundle of local Grain Tickets, the smallest of which was a half-kilo and the largest was five-kilo. As she expected, they were exclusive to this city and couldn't be used outside of it. Since they were not all for refined grain, the summed total was thirty kilos.
Ten kilos of refined grain, twenty kilos of coarse grain.
According to national standards, twenty kilos of coarse grain can be equivalent to five to six kilos of refined grain.
