As a sister, you should protect your brother. Although I often quarrel and even fight with my brother, after all, I am the treasure of my family. If I want to bully myself, I can only bully myself. If I am bullied by outsiders, I naturally can't swallow this tone. This is my natural desire for protection as a sister, and it is also the hub of emotional communication between brother and sister. However, when being bullied, the specific approach also depends on the situation. There is no doubt that as a sister, I will never sit idly by when my brother is bullied.
