Brothers and sisters can't be 1 1 years old, can they? Because if the difference between brother and sister is 1 1 year old, the younger brother's daughter will have to be called sister and grandmother, right? Haha, there is no such logic. In recent years, with the loosening of the population policy and the opening of the second child policy, more and more families have chosen a second child on the premise of economic affordability. The age difference between brothers and sisters in many families is far above 1 1 year. Although it seems strange when traveling in a family, even the elder sister can take care of the younger brother alone, but the younger brother's children can only call her aunt, and it doesn't make any sense to call her grandma.
