Compared with the above resume, this work is a work four feet apart, which reads: Yuanyuan is a running script, with smooth pen and ink, beautiful words and ancient words, taken from Erwang; Inscription time: "Ren Yin Xia" is written in cursive, taking two French kings and written this summer; Signature: It is written in cursive script, and the words "Chen" and "supporting the army" are separated, which is wonderful. After consulting other works, this is a common writing method used by teacher Chen; Moreover, the left and right spacing of the word "Chen" is opened, which also creates a brushwork for Teacher Chen; The last two seals: one is Chaoyangge (Mr. Chen Yongjun's Zhai Hao) and the other is Chen Yongjun; To sum up, it can be inferred that the word "Yuanyuan" was written by teacher Chen Yongjun. Disadvantages are for reference only. Thank you.
