What are some examples of gratitude in history?
When Han Xin was a teenager, his family was poor and his parents died. Although he studies hard and practices martial arts hard, he still has no life. As a last resort, he had to go to other people's homes to eat for free, which was often ignored by others. Han Xin swallow not to descend this tone, went to the Huaihe River to fish, fish for food, and often had a hearty meal. There is an old woman who washes yarn wadding for others by the Huaihe River. She is called "floating mother". Seeing Han Xin's pity, she gave him her own food. Every day, without interruption. Han Xin was deeply moved. Han Xin, who was named the marquis of Huaiyin, never forgot the kindness of his wandering mother, sent people to look around and finally gave it to him as a gift.
