This poem is called "Painting Screen Poems", also called "Twenty-five Painting Screen Poems (Fourteen Poems)", which contains 25 ancient poems written by Yu (Y incarnation) in Wei, Jin, Southern and Northern Dynasties. There are many pictures on ancient screens or fences.
This poem was written by the author when he was in Liang, and it all describes the paintings on the screen. Although the screen at that time no longer exists, we can understand the general content of the screen painting at that time from the poem.
Yu Xin was a servant of Liang Xiangdong in his early years, and accompanied Prince Xiao Gang (Emperor Liang Jianwen) and others to write some gorgeous poems. In the last years of Liang Wudi, Hou Jing rebelled. When Yu Xin made a health order, he led the troops against the enemy and suffered a heavy defeat. After the fall of Jiankang, he was forced to flee to Jiangling and defected to Xiao Yi, Emperor of Liang Yuan.
In 554 AD (the third year of Yuan Di's reign), he was ordered to go to the Western Wei Dynasty. Shortly after he arrived in Chang 'an, the Western Wei Dynasty occupied Jiangling and killed Xiao Yi. Staying in Chang 'an, the official arrived at the title of generals in ancient times and was the third division, so it was also called "Yu Kaifu". Yu Xin was forced to stay in Chang 'an and bid farewell to Jiangnan. His heart is very painful. Coupled with his wandering life, his thoughts and creations have undergone profound changes before and after his mission to the Western Wei Dynasty.
Before Yu Xin went to the Western Wei Dynasty, there were not many works, and he did not get rid of the influence of "palace poems" on the whole. Up to now, most of the poems and poems that have been recited are written by him after he went to the north. These works are different from his early works in terms of ideological content and artistic style.
