The meaning of the second fish theory

Fish is a symbol of good luck. The ancients have long suggested that fish has a "surplus" every year, and it is prosperous. A general meaning of fish is to be together, to be inseparable from you, and to like being with you for life. One is that I hope you can take good care of yourself and be happy forever, but there is no love. Two or three is to be together for life and never part. The two are plain, want to be with you, and have no distractions; Third, I hope to destroy my rival in love, set you free, and prove that there will be silence to accompany you.
