Who is the emperor of the palace with thousands of doors open in broad daylight?

Li Longji, Emperor Xuanzong of the Tang Dynasty, had thousands of palace doors open during the day. The palace opened by thousands of doors in the daytime comes from the Ming King's Play Map written by Chao Shuo, a poet in the Song Dynasty. A palace with thousands of doors open during the day means there are thousands of doors open in the palace.

The poem "The Map of Ming King Playing Ball" describes the story of Li Longji playing polo in Xuanzong of Tang Dynasty. The content of the poem is that the palace is open during the day, and Saburo is intoxicated with playing ball. Han Hugh died at the age of nine, and there should be no hint tomorrow. This means that the palace gate is open during the day, and Saburo Li Longji has just returned from playing polo drunk. Zhang Jiuling is dead, and there will be no more admonitions sent to the palace tomorrow.

Extended data:

The poem "The Map of the Ming King Playing Ball" satirizes the historical fact that Emperor Xuanzong of Tang Dynasty craved pleasure and missed his motherland in his later years. Zhang Jiuling and Han Xiu are men of insight who dare to speak and remonstrate, and were later slandered by the traitor Li. Later, Xuanzong indulged in sensual pleasure, and his politics declined, which eventually led to chaos. The word "drunk playing ball" vividly depicts the appearance of drinking and having fun.

This poem expresses the poet's feelings about reality by reciting historical facts in paintings. The first two sentences are about the rising weather with the palace gate wide open in the Tang Dynasty and Xuanzong's triumphant appearance after playing football. The last two sentences are that the poet is venting his resentment, which is not only a satire on Tang Xuanzong, but also a praise and regret for loyal ministers.
