Confucius said, "Zhilan was born in a deep valley, and it is not without people. A gentleman cultivates morality. Don't change festivals for the sake of poverty. Since then, orchids have become the representative flowers in the hearts of Confucian scholars. Orchids will be loved by people mainly because of their clear fragrance and elegant posture. The most important thing is that they were born in a deep valley of a forest stream. The so-called empty valley gives birth to orchids. The most important thing for orchids is "seclusion", because they only have that elegant fragrance when they are born in a valley. Once they leave "seclusion", they will inevitably be polluted by dirt. Under this circumstance, orchids are endowed with the image of a hermit in Gaode, a kind of recluse who is far from official career, does not seek fame, and does not seek fame.
