Fortunately, by the river where he often fishes, there are many floating mothers (old women cleaning silk cotton wool or old clothes and fabrics) working. Give him food. Han Xin, in the midst of difficulties and hardships, was favored by her wandering mother, and she could barely make ends meet with her hands. He was very grateful to her and told her that he would be rewarded in the future.
