"Newly promoted horse" comes from the grading competition of horse racing, and rises from the low-level group to the high-level group to participate in the competition. Such "horse racing" is called "newly promoted horse".

Other sports league events that are now extended to graded competitions, such as the top two in the first-class football league, will be promoted to the Super League next year. In next year's Super League, these two teams will be called "newly promoted horses".

The promotion is from the lower league.

Many terms in football were originally borrowed from other sports. For example, hat tricks were borrowed from cricket.

At that time, horse racing was very mature, and some modern sports had just started, so it was natural to borrow some terms and even rules. There are different opinions about the origin of the word "advanced horse", but it is generally believed that it originated from the racecourse and refers to the horses that originally participated in the low-level horse racing. Because of their excellent performance, people call these horses "newly promoted horses". People introduced this into football, so on the court, the team that just rose from the low level to the high level was called the newly promoted horse.

The first sheep (that is, the leader of the flock) is always at the front of the flock. This is the so-called leader. Other sheep will consciously follow the leader, and the shepherd only needs to lead the leader, so we call the team leading the standings the leader.
