Holding a bunch of flowers in your hand is better than all romantic poems. What do you mean?

"Holding a bouquet of flowers is better than all romantic poems" means holding a bouquet of flowers for your partner, which is better than just telling each other any romantic poems. Expressing love for a person is also more practical than just saying sweet words. No matter how nice it is, it is all empty talk, and even a small moving action is not worth it.
