As soon as the materials were hoed, it was noon, and sweat dripped down the soil. Who knows that every grain of Chinese food is hard?

Even if calculated conservatively, at least 200 million people's annual rations will be dumped every year. At the same time, hunger is still the number one killer of mankind. On average,10 million people die of hunger every year in the world, and a child dies of hunger every six seconds.
