訇弟弟和我是孪生姐弟，老妈说我俩生下来的时候，我体重4斤才差一两，弟弟只有2斤9两还多一两。我很关心当时用什么样的秤来秤小毛牙，老妈说痛昏过去了，没注意。弟弟怀疑是卖水果那样的盘秤，把小孩用布一裹（甚至不裹，能称出净重），往秤盘上一掇，左手捏秤头，右手校准星 My brother and I are twin brothers. When my mom said that when we were born, I would only lose 1 or 2 pounds in weight, and my brother would only have 2 pounds and 9 or more. I was very concerned about what kind of scales were used to scale small teeth. My mother said that she was fainted and did not pay attention. The younger brother suspects that it is a disc scale that sells fruits. The child wraps the cloth with a cloth (or even does not wrap it, and can weigh the net weight). He weighs it on the weighing pan, and the left hand squeezes the scale and the right hand aligns the stars.
