Is it the abbreviation of Silence in Zhiruo Youlan? It shows an elegant and tranquil artistic conception, quite like a scholar-bureaucrat in the Jin Dynasty. Both "Zhi Ruo" and "Lan" were regarded as lofty symbols by ancient people in China, a bit like Chun Xue. Here, if we say that zhi ruo is quiet and silent, I think it means that lofty people speak fresh. You are describing waves. Since there are waves, there should be no silence.
