In the classical Chinese of Gao Sicheng's Bai Ting Fu, the author illustrates Bai Juyi's advantages and Gao Sicheng's disadvantages in a comparative way. Please briefly summarize them separately?

Bai Juyi is gentle, quiet and humble, considerate, obedient to fate, not happy because of praise, not anxious because of embarrassment. He is the kind of person who can be comfortable anywhere! Bai Juyi's poems are easy to understand, express natural interests directly, conform to natural principles, satisfy his own ideas, and never pretend to stimulate the senses of secular people.

Gao Sicheng is now thinking about being an official and making a fortune all day, eager for promotion, and struggling with the idea of gain and loss. This can't be compared with Bai Juyi Gao Sicheng's poems are blindly carved and whitewashed, which inevitably reveals exaggerated indulgence and cannot be compared with Bai Juyi.
