There are two children in my family. I am the second child in my family, and I have a sister on it. Because my parents didn't have a son, I was angry with my family, and even my grandparents didn't like us. Later, when I was in high school, my father could not do heavy work because of physical reasons, so my mother basically maintained the living expenses at home. However, the lives of uncles and aunts are getting better and better, and the gap between us and their families is getting bigger and bigger.

Maybe it's because of family conditions. My sister hasn't studied since she graduated from high school, saying that she is not the material for studying at all. It is better to come out early to earn money to subsidize the family. Actually, I know my sister just wants to support this family. My sister is not only tall, but also good-looking, so she found a sales job outside. She said the salary was ok.

A few years later, the house was decorated, I went to college, and the living conditions at home were finally good. During the period, many people introduced my sister, but all of them were rejected by my sister, saying that I didn't want to think about it yet. Then at the age of 28, my sister made a boyfriend. I heard it's one of her clients, and her family conditions are OK. Our family is very happy about it. We feel that my sister has worked hard for most of her life, and now she can finally live a comfortable life. But the man's house is far from ours, so the wedding was held directly at his brother-in-law's house, and our house went on the wedding day.

The wedding was held in the hotel over there, and people from the wedding company were invited. There are always more than a dozen banquets, which look very lively. Later, I accidentally saw my sister wearing a wide bracelet, which didn't match her temperament and was very clear about her preferences. She never likes to wear these things, but my sister keeps them. I felt very strange at that time, so I carefully examined my sister's wrist. Unexpectedly, there is a red and swollen wound on her wrist, which looks like a knife wound.

Suddenly I felt something was wrong, so I asked my sister what happened to the injury on her hand. After repeated pestering, my sister told us the truth. It turns out that my brother-in-law is prone to domestic violence and has a strong desire for control. I advised my sister to reconsider this marriage, but she said that we all received a bride price of 1.8 million, which was almost spent. Now that we are pregnant for two months, it is too late to go back on our word.

Later, my sister asked me not to tell my parents about it, saying that I was young and there were many things you didn't understand. Looking at my sister's helplessness, I was speechless with mixed feelings. Now junior year. Sometimes I see this situation at home and think that my sister has sacrificed so much for this family, so I hate myself for bringing trouble to this family. But I am also very helpless and don't know what to do. And I'm worried that my sister will do something stupid for this family, so I call her every day and chat with her. This is the only way I can help my sister. What do you suggest I do?
