In the story of a seed, Grandpa Xie told me that it was not easy. In those hard years, "a bowl of porridge" became a luxury. It was this group of scientists who made silent dedication to make every family in China have enough to eat and eat well. Their dream was no longer "a bowl of porridge". Time is invisible, but I saw the trace of sunshine in Grandpa Xie's hand. The years are seamless, but I see the firmness of a generation in Grandpa Xie's eyes! When the world suffers from environmental degradation, abnormal climate, local wars and epidemic spread, we should also save food, establish a sense of crisis and cherish every hard-won grain.
