What did I learn after reading Seven Diamonds?

Today, I read the story Seven Diamonds. This story tells of a little girl holding a wooden pitcher to find water for her sick mother. After finding water, she kept giving it to the animals and people who needed it first. The wooden pitcher became a silver pitcher, a golden pitcher and finally a spring. The little girl no longer has to look for water. Seven diamonds jumped out of the pitcher and became the constellation Ursa major. After reading this story, I understand a truth, that is, helping people who need help more than themselves will receive unexpected gains. At the same time, it also taught me: don't just care about immediate interests, don't be selfish, think of others first, and in the end, you may benefit the most!
