The last month has been the busiest time of year for Li Yingwen and his fellow grain farmers.
The tasks include testing combine harvesters, looking for labourers, supervising the reaping and spreading out the grain in the sun. Soon, Li will find himself dealing with rice traders from across the country.
Li's family grows about seven hectares of rice on farmland he rents from the state-owned Lianjiangkou Farm, which leases 180 square kilometres of land to farmers in Heilongjiang province, a major grain-production base.
Thanks to good weather, he expects a bigger-than-usual harvest of more than 80 tonnes this year, up from less than 60 tonnes last year.
Li keeps only a small portion of the grain in reserve for his family's needs, with more than 95 per cent sold to rice traders. After several rounds of trading, the bulk of his harvest will finally get to food markets in neighbourhoods, or end up at the government's grain-storage depots.
The central leadership decides how much grain should be bought from the market and stored in state-run grain depots each season, and the State Council entrusts the state-owned China Grain Reserves Corporation (CGRC) to oversee the nation's grain reserves.
