Sun Yitong found an abandoned baby, Mingming, at the age of twenty and single-handedly carried cement to raise her. When her daughter was admitted to Tsinghua and Peking University but could not gather the tuition fees, Yang Ling, the down-and-out businessman she had helped back then, returned as the chairman of the Yang Group. He moved in next door under an assumed name, secretly helping her, protecting her dignity, and settling scores with the bullies, all to repay the life-saving grace of that bowl of noodles and 500 yuan ten years ago.
