What kind of feelings does Zhang Jingzhong express in his whole poems?

Writer's Sketch Zhang Jingzhong was a little-known poet in the early Tang Dynasty. He is an official who supervises the imperial history and is famous as a literary official. In Kaiyuan, he was the messenger of Pinglu. There are only two poems recorded in the whole Tang Dynasty. According to "Biography of Zhang Renyuan in the New Tang Dynasty", in 707 AD, when Zhang Renyuan was appointed as the general of Shuofang Army, Zhang Jingzhong, who was then the censor, was employed. This song "Bian Ci" is probably his work when he released the military curtain. The "Wuyuan" in the first sentence of the boutique is located in the desert, facing the desert in the north, with a cold climate and desolate scenery. Spring here never comes very late, so there is a saying that "Wuyuan is always late in spring". The word "Lao Lai" not only shows the desolation of Wuyuan since ancient times, but also shows that poets have heard about it for a long time. This sentence is the general outline of the whole poem, and the next three sentences are a concrete description of the late arrival of spring scenery. "In February, weeping willows don't hang silk." Every February, the bare weeping willows have not yet vomited leaves and hung silk. In mid-spring and February, the mainland is already pink and green, and the spring is brilliant, but there is no breath of spring here. Willow color has always been a symbol of spring, and poets always find the meaning of spring in willow color first, and find the footsteps, sounds and figures of spring. Zhang Jingzhong also grasped the typical image of "weeping willows don't hang silk", and wrote the characteristics of late spring in the border region very concisely and vividly, making people seem to see several weeping willows swaying bare branches in the vast desert and fierce cold wind. Three or four sentences are still closely related to Spring Festival Evening, but written from another angle. By comparing the different scenery of Wuyuan and Chang 'an, the late spring in the north is highlighted. Today, the river ice has just thawed, and the footsteps of spring are faintly audible. I think Chang 'an is in full bloom. The ice by the river and the autumn flowers in Chang 'an suggest that this season is already worth late spring. In the desolate north, the river ice has just thawed at this time. Although the footsteps of spring are faintly audible, the figure and color of spring are still not seen. The capital Chang 'an has long lost its breath of spring. This contrast not only further highlights the late spring of the frontier, but also contains the homesickness of the soldiers guarding Chang 'an, the desolate capital of the north. Ice by the River brings people the prospect of spring, and spring will come eventually. The characteristic is that this poem should be scattered, knotted and distinctive. In particular, the combination of an artistic conception and a pair of seemingly just-right flowing water makes people feel that the author is treating the scenes of "spring scenery is old and late" and "weeping willows don't hang silk" with a calm mind. Before "The Day when the Ice Opens on the River" and "When the Flowers Fall on Chang 'an" meet neatly, words like "today" and "yes" were used to echo each other, forming a style of looking around at will, which is typical of the early Tang Dynasty.
