《早朝》(Zǎo Cháo) by Táng Dynasty (唐, 618 - 907) poet 王维 (Wáng Wéi)
陆游 (Lù Yóu) was a great poet from the Southern Sòng Dynasty (南宋, 1127 - 1279). He was successful enough to become a government official, but his opponents in court repeatedly told the emperor that he spent all day slacking on the job and writing poetry, and he was eventually dismissed.
After his dismissal, a furious 陆游 returned home. A few years later, he traveled to Shānxī Province (山西) to visit a friend. When his friend and his friend's neighbors heard that 陆游 had arrived, they all warmly received him by throwing a large banquet. The poet was deeply moved by this, especially considering the genuine display of warmth was so different than the airs of the politicians that he'd been dealing with in his career.
Later, 陆游 wrote the poem《游山西村》(Yóu Shān Xī Cūn) to commemorate his experience. The chengyu 柳暗花明 was part of the poem.
