What emotions do Bai Juyi and Ma He Zhu express when sending guests back to Beijing?

In Bai Shi, there is both concern and admiration for his friend's return to the capital, as well as his frustration and despair, his desire to be reused by the king, and his high hopes for his friend. The poem expresses his love for landscapes and scenery, his indifference to fame and fortune, but his helpless distress of being inextricably bound and unable to return to the countryside.
