After 17 years of marriage, the rose is considered to be a symbol of romantic love as well as physical love. Using the rose as an analogy to the marriage of the couple, it means that after 17 years of marriage, there will be a lot of quarrels and frictions, just like the thorns of the rose, but even so, the two sides still love each other, just like the petals of the rose. There are quarrels and sweet things, but the couple will always work together.
