For example:

1, I think this is the little beauty in life. My brother feeds my sister, which makes me feel very warm and happy.

Their brother and sister are very happy together. My brother feeds my sister, which makes me feel that my brother has really grown up and knows how to help my mother take care of my sister together, which makes me feel very gratified.

My brother supports my sister, which is a kind of care, which is all the care for my sister, and which is all the warm happiness in the family.
