What is it like to marry a child bride? A netizen: I burst into tears like a dog yelping

My grandmother seems to have been a child bride too. When my grandfather was young he was very handsome, but my grandmother was short, though not bad-looking; her family was just too poor to feed her, so she was given to my grandfather as a child bride. My grandmother gave birth to seven children, and my mother was the youngest, though all my uncles and aunts in the family inherited my grandfather's good genes.
Let me tell you about one where both families used to live halfway up the mountain. Different surnames. The two families lived very close. The girl's family had an older sister above her and a younger brother below her, so you could say she was not favored; later both families moved down the mountain, just a little above my house. The boy was about ten years older than the girl, disobedient, what the countryside called a small-time troublemaker, short and bald, and he could not find a wife, so his family said they would have that girl marry their son. They got married, and the two families were a one-minute walk apart, so she could go back to her parents' home anytime..
I heard my grandmother say that child brides in their era were very pitiful. In one family, a child bride did not watch the congee carefully while cooking it, and the congee boiled over; when the parents-in-law came home, they directly scalded the child bride to death with the congee. My maternal grandmother was also a child bride. She passed away before I was born. I heard from my mother that my maternal grandmother was very pitiful and had no say at all, and my maternal grandfather was very selfish.
My husband and I were childhood sweethearts and had a betrothal arranged when we were children. We grew up playing together, very close, going to school, eating, and everything, and even sleeping together when we were little; we were stuck together every day. By the time they were having puppy love, we were already an old married couple.
When my wife was little, her family was very poor. In the early 1990s, her family often had only a few yuan. But my family had two working adults, and my maternal grandfather ran a restaurant, and he gave me 20 yuan a week in pocket money. My wife said it would have been great if she had been a child bride in my family back then, so the pocket money could have gone to her.
There is one around me. She was brought back when she was over ten years old, and her parents-in-law treated her like their own daughter. But her husband cheated on her, and she did not even have any family of her own to turn to. Fortunately, her parents-in-law were reasonable and stood on her side.
