Because butterfly is homophonic with "crouching", it is often regarded as the meaning of "crouching to death" in Feng Shui. If there are butterflies flying at home, it means that something good will happen at home and people at home will be blessed. Because under normal circumstances, if the season is not good, butterflies will not fly to places where people live, unless this place is so blessed that butterflies can't help but want to be blessed.
If butterflies fly in pairs, it means that the relationship between husband and wife in the family will be beautiful, because the butterflies in pairs represent the loyalty of love in Butterfly Lovers.
Represents feelings:
Irises all appear in pairs, so they also symbolize sweet love and happy marriage. Liang Zhu Becomes a Butterfly says that after Liang Zhu and his wife died at the same time, they became beautiful butterflies and stayed together forever. I think everyone has heard the classic story of Liang Zhu becoming a butterfly. Since ancient times, their sad emotional stories have touched generations.
So iris is also loyal, which means that two people who love each other are loyal and keep their promises. In ancient times, people often turned iris into a beautiful fairy to help people tide over disasters, which gave iris a mysterious color, which meant that it could avoid disasters.
