Guanglao's point of view: the teacher is a father all his life, that is, the teacher is a generation older than us. Although there are brothers and sisters in the same school, there are few uncles and uncles, but this does not affect the intergenerational relationship, that is, brothers and sisters are brothers and sisters of the master, uncles and uncles are peers, so there is little intergenerational education in the field of mentoring. So your brother and sister are not your own brothers and sisters, nor your peers' brothers and sisters, so it is more appropriate and correct for you to be a sophomore, so you are called a freshman.
