As follows:
1. Siblings are like waves and vines. It is difficult to move forward even if you throw away the waves and the vines.
2. My sister is the one who helps you wash your dirty clothes and fold them neatly.
3. My sister is a person whose family is not rich, but she is willing to spend her pocket money with you.
4. A sister is someone who can collect money from everywhere to help you when you encounter difficulties, and never expects you to pay it back.
5. My sister is the kind of person who squeezes two people into the same bed. You kick her to the ground, she covers you with a quilt, and then she sleeps on the floor.
6. "Sister-sister" is always a sweet responsibility, never an opportunity.
