Fish Leap Dragon Gate symbolizes a successful career or a high position, and is also a metaphor for moving forward against the current, upward, a symbol of good luck. According to folklore, carp is a kind of spiritual fish, symbolizing opportunities, fortune and so on, expressing people's aspirations for a better life, and leaping through the Dragon Gate to become a dragon makes this symbolism even more significant.

Fish leaping over the Dragon Gate in the old days indicated the great joy of being successful in the imperial examination, promotion, etc., and then extended to go against the current, the meaning of upward mobility. The word has been passed down to this day, and the positive connotations of the word still remain, and on this basis it has given rise to such beautiful symbols as the success of young people's careers and the fulfillment of their dreams. The word comes from the Xin's Sanqin Chronicle, in which the Yellow River carp is said to have become a dragon after jumping over the Dragon Gate, which is now known as Yumenkou.

Notes and highlights of idioms:

Many people have heard all kinds of stories when they were young, such as the well-known "Snow White", "The Emperor's New Clothes" and so on, and so far it is still a household name, but also "Carp jumped over the Dragon Gate". The story describes how a small carp can change into a dragon after jumping through the dragon gate, and it also symbolizes people's determination to move forward against the current.

While the legend of the carp jumping over the Dragon Gate is implausible nowadays, and it's unlikely that any such change of species would occur. But in fact, we just use such stories to inspire people's fighting spirit power, but also represents a kind of good wishes of people.
