Who Hears the Broken String?

The moon in the sea sheds tears, and the warm sun in Lantian produces smoke. The only thing left in history is their long sigh. The years are like layers of fog, covering up the truth of history one by one, making it difficult for us to see clearly. But this sigh makes us believe that more than a thousand years ago, what kind of young and beautiful lives there were, and what kind of love and hate they had! They once had such passionate love, such deep sighs, such heart-wrenching regrets... The moon has been full before, but love eventually broke up.
