Cicada is far away from cicada because cicada is on a tall tree, not relying on autumn wind. -Yu Shinan, a famous sage, calligrapher and poet in the Tang Dynasty, wrote the poem Nian Chan. ? "Hang Yi drink clear dew, flow ring out sparse tung. It's not the autumn wind that makes you afraid to speak loudly. " This is an object-chanting poem by Yu Shinan, a famous minister in the early Tang Dynasty, which is full of symbolic significance. Every sentence describes the shape, habit and sound of cicada, and every sentence implies the poet's noble character and interest. The deep meaning of chanting things is to praise people. The implication of these poems is that an official should stand tall and be virtuous in order to speak loudly and have a good reputation.
