Please illustrate the implicit beauty of poetry with examples.

Classical poetry pays attention to implicit beauty, so puns are widely used. Puns can be divided into homophonic puns and semantic puns. Pun means saying one thing, meaning another, which makes the expression more subtle and interesting. For example:

(1) Lower your head to get the lotus seeds, which are as clear as water. Hide lotus seeds in your sleeve. Lotus seeds are red and transparent. "Lotus seed" is a homophonic pun, meaning "Reiko Kobayakawa" and "Love you".

Silkworms in spring will weave until they die, and candles will drain the wick every night. (Untitled by Li Shangyin) The Sound of Silk and Thinking: The word "tears" is a semantic pun, which clearly refers to wax tears, but it implies the tears of acacia.

(3) Sunrise in the east and rain in the west, the road is sunny but sunny. (Liu Yuxi's Zhi Zhu Ci) Sound "sunny" and "emotion" actually refer to feelings.
