Excuse me, is this banner Chen Yongjun's calligraphy?

1. The first sentence "White Wall and Qingwa Old Street School" is a cursive brushwork, and the brushwork is two kings, which conforms to the characteristics of noble, elegant and classic cursive lines for supporting the army; 2. At the end, "Laughing and holding cups in the Shuige room" is also the writing style of the second king Lu Yi, but some words are taken from the brushwork of Huang Tingjian and others; 3. The word "oblique" in the second line and the word "middle" in the fourth line account for three or four words, which are the highlights of Chen Yongjun's creation and the finishing touch of his works, in line with his consistent writing style; 4. The leftmost inscription: Guimao Daxue (meaning it was written in the spring of the heavy snow solar term in 2023), Chaoyangge (Chen Yongjun Zhaihao Chaoyangge, refer to the following introduction), with the word "Erwang" as the cursive script, and the cursive script of "Chen Yongjun" conforms to Yong Jun's usual cursive script, and there is a word distance between the two words, so it follows the fate freely. 5. Two seals: one is Chaoyangge (Chaoyangge, house number, Chen Yongjun, refer to the following resume), and the other is Yongjun's private seal. To sum up the five points, it can be inferred that this cursive script should be a calligraphy work of the poem Xieqiao Ancient Town in Haining written by Chen Yongjun, for reference only. Teacher Yong Jun is famous for her virtue and artistry, good character and artistic quality of Shang Gao. She is keen on calligraphy public welfare and has made great contributions to calligraphy education in Guangdong universities. Please forgive my lack of analysis, thank you.
