There is no "Private Door Tie", only "Meng Nei Tie" written by Wu Shuo, let me introduce it; "Meng Nei Tie" is a storyteller written by Wu in the Northern Song Dynasty. Paper. Running script, letters. Fourteen lines, one hundred and forty words. The calligraphy is round, beautiful and smooth, and the pen is clean and healthy. This painting is followed by a postscript by Qing Weng Fang Gang. It was collected by Bi Chen, Jiang Deliang, Yong Li and others of the Qing Dynasty. Recorded in "Pei Yu Ou Ji". Now in the Palace Museum. Sorry, the original text has been lost. Wish you good luck
